Description
Fremgangsmåte ved f remstilling 'av pyrido-Q 2 , l-b3 - kinazolinonderivater
Foreliggende oppfinnelse angår fremstillingen av terapeutisk aktive pyrido-[2,l-b]-kinazolinonderivater med den generelle
formel I ifølge krav 1, såvel de racemiske derivater som deres optisk aktive antipoder..
Som fysiologisk godtagbare salter av carboxylgruppen X i formel I kan eksempelvis nevnes alkali- og jordalkalimetallsaltene, som natriumsaltet eller calciumsaltet, ammoniumsaltet, kobber(II)-saltet eller raethylglucaminsaltet, såvel som saltene av disse forbindelser med aminosyrer.
Fysiologisk godtagbare alkoholer som carboxylgruppen.X i formel I kan være forestret med, er f.eks. rettkjedede, forgrenede eller cycliske, mettede eller umettede hydrocarbongrupper, som eventuelt kan være avbrutt av et oxygenatom eller et nitrogenatom, eller kan være substituert med hydroxygrupper, aminogrupper eller carboxylgrupper, (fortrinnsvis slike med 1-12 carbonatomer og særlig slike som har 1-6 carbonatomer) som f.eks. alkanoler, alkenoler, alkynoler, cycloalkanoler, cycloalkylalkanoler, fenyl-alkanoler, fenylalkenoler, alkandioler, hydroxycarboxylsyrer, aminoalkanoler eller alkylaminoalkanoler og dialkylaminoalkanoler med 1-4 carbonatomer i alkylgruppen.
Alkoholer som er egnet til forestring med carboxylgruppen,
er eksempelvis slike som har en methyl-carboxymethyl-, ethyl-, 2-hydroxyethyl-, 2-methoxyethyl-, 2-aminoethyl-, 2-dimethylamino-ethyl-, 2-carboxylethyl-, propyl-, allyl-, cyclopropylmethyl-, isopropyl-, 3-hydroxypropyl-, propinyl-, 3-aminopropyl-, butyl-, sek-butyl-, t-but yl, butyl-(2)-, cyclobutyl-, pentyl-, isopentyl-, t-pentyl-, 2-methylbutyl-, cyclopentyl-, hexyl-, cyclohexyl-, cyclo-2-enyl-, cyclopentylmethyl-, heptyl-, benzyl-, 2-fenylethya-, octyl-, bornyl-, isobornyl-, menthyl-, nonyl-, decyl-, 3-fenyl-propyl-, 3-fenyl-prop~2-enyl-, undecyl- eller dodecylgruppe.
Som til forestring egnede alkoholer kommer også slike' i'"' betraktning som fører til labile, dvs. under fysiologiske betingelser spalt-bare, estere, som 5-hydroxyindan, acyloxymethanoler, særlig acetoxymethanol, pivaloyloxyraethanol, t -indanylbxycarbonylmethanol glycolsyre, dialkylaminoalkanoler, særlig dimethylaminopropanol, såvel som hydroxyfthalid.
Som fysiologisk godtagbare aminer, med hvilke carboxylgruppen'kan være amidert, kommer fortrinnsvis alkylaminer, dialkylaminer, alkanolaminer, dialkanolaminer med 1 - 6 carbonatomer i alkyl-eller alkanolgruppen eller 5- eller 6-leddede N-heterocycler i betraktning. Som egnede aminer kan eksempelvis nevnes: methyl-amin, ethylamin, isopropylamin, ethanolamin, dimethylamin, diethyl-amin, diethanolamin, pyrrolidin, piperidin, morfolin eller,N-methylpiperazin.
Salter av pyrido-[2,l-b]-kinazolinonderivatene med den generelle formel I med fysiologisk godtagbare baser er eksempelvis alkalimetallsalter eller jordalkalimetallsalter, som natrium-saltene eller calciumsaltene, eller ammoniumsalter, kobber(II)-salter, methylglucaminsalter, piperazinsalter, eller saltene av disse forbindelser med aminosyrer.
Som pyrido-[2,l-b]-kinazoliniumsalter av forbindelsene med den generelle formel I kommer eksempelvis hydrokloridene, hydro-bromidene, sulfatene, fosfatene, oxalatene, maleatene, tartratene eller eitratene i betraktning.
Pyrido-[2,1-b]-kinazolinonderivatene med den generelle formel I er farmakologisk virksomme forbindelser eller mellom-produkter til deres fremstilling. De farmakologisk virksomme forbindelser utmerker seg særlig ved sin antiflogistiske, anti-pyretiske, analgetiske og antiallergiske virksomhet. Dessuten be-virker disse forbindelser in vitro en utpreget fosfodiesterase-hemning. Mavens toleranse overfor de virksomme pyrido-[2,1-b]-kinazolinonderivate.r er relativt god, deres toksisitet er relativt lav.
De farmakologisk virksomme forbindelser egner seg. i kombina-sjon med de i den galeniske farmasi vanlige bærere til behandling f.eks. av akutte og kroniske inflammasjonsprosesser, polyarthritis, neurodermitis, asthma bronchiale, høyfeber o.a.
Fremstillingen av legemiddelspesialitetene skjer på vanlig måte idet virkestoffet med egnede tilsetninger,
bærere og smakskorrigenser overføres til de ønskede applikasjons - former som tabletter, dragéer, kapsler, oppløsninger, inhalerings-midler osv.
For oral anvendelse egner seg særlig tabletter, dragéer og kapsler som eksempelvis inneholder 5 til 500 mg virkestoff og " 50 mg til 2 g farmakologisk virksomme bærere, som f.eks; lactose, amylose, talkum, gelatin, magnesiumstearat' og lignende, såvel som de vanlige tilsetninger.
Fremgangsmåten ifølge oppfinnelsen for fremstilling av pyrido-[2,1-b]-kinazolinonderivatene ifølge krav 1 utføres under betingelser som er vel kjent for en fagmann (Ullmann-reaksjonen). Som utgangsforbindelser for denne fremgangsmåte anvendes fortrinnsvis slike pyridinderivater med den generelle formel'II som som sub-st ituent Y har en aminogruppe, et kloratom, et bromatom, en alkoxy-gruppe med 1-4 carbonatomer i alkylgruppen, en trimethylsilyloxy-gruppe, en methansulfonyloxygruppe eller en p-toluensulfonyloxy-gruppe. De som utgangsforbindelser anvendte fenylderivater med - den generelle formel III har fortrinnsvis som substituent V et hydrogenatom eller en alkylgruppe med 1-4 carbonatomer, og som substituent Z en aminogruppe, et kloratom eller et bromatom. Alkoxycarbonylgruppen i forbindelse III er fortrinnsvis grupper med 1-4 carbonatomer i alkylgruppen.
Reaksjonen utføres fortrinnsvis idet man oppvarmer reaksjons-deltagerne, eventuelt i et høytkokende oppløsningsmiddel (som f.eks. ethylenglycol, ethylenglycol-monomethylether, ethylenglycolmonobutylether eller ethylenglycol-diethylether) i nærvær av baser med kobber- eller zink-katalysatorer ved 100 - 250°C. Egnede baser er eksempelvis alkalicarbonater (natriumcarbonat eller kaliuincarbonat) eller høytkokende tertiære aminer (N-ethylmorfolin, N-ethylpiperidin, etc.). Som egnede kobber- eller zink-katalysatorer kan eksempelvis nevnes zink(11)-klorid, kobber - pulver, kobber(I)-oxyd, kobber(II)-oxyd, kobber(II)-klorid, kobber(II)-sulfat eller særlig kobber(II)-bromid og kobber(I)-bromid.
Fremgangsmåten ifølge krav 2a} skjer likeledes under betingelser som er vel kjent for en fagmann. Således kan nitrilene, eksempelvis med sterke mineralsyrer (som saltsyre eller svovel syre) eller med sterke baser (som vandig natronlut eller kalilut) hydrolyseres delvis til de tilsvarende amider eller under hårde betingelser til de tilsvarende carboxylsyrer.
For disse reaksjoner kan den vandige.mirieralsyre eller base selv anvendes som oppløsningsmiddel. Det er imidlertid på den annen side også mulig å utføre reaksjonen i nærvær av polare opp-løsningsmidler som f.eks. lavere alkoholer (methanol, ethanol, isopropanol, etc), carboxylsyrer (eddiksyre, propionsyre, etc), polare ethere (glycolmonomethylether, dioxan, tet rahydrof uran, etc) eller dipolare aprotiske oppløsningsmidler (dimethylsulf oxyd, etc).
Vanligvis utføres hydrolysen ved en reaksjonstemperatur på 20 - 160°C.
Utgangsforbindelsene med den generelle formel Ia anvendt for denne reaksjon, kan fremstilles ved fremgangsmåten ifølge krav 1'• eller 3.
Fremgangsmåten ifølge krav 2b) utføres likeledes under betingelser som er vel kjent for fagfolk. Denne reaksjon utføres ved termisk oppvarmning av malonsyrederivatet med den generelle formel IV til 50 - 150°C, idet decarboxyleringen kan utføres uten et oppløsningsmiddel eller i nærvær av et høytkokende oppløsnings-middel (som xylen,.klorbenzen eller decalin).
Utgangsforbindelsene med den generelle formel IV anvendt for disse fremgangsmåtevarianter, kan eksempelvis fremstilles som følger: pyrido-[2,1-b]-kinazolinonderivater med den generelle formel i hvor R, er hydrogen, og X er en cyanogruppe eller alkoxy-carbonylgruppej omsettes med natriumhydrid i diethylcarbonat. Overskudd av oppløsningsmiddel avdestilleres, og det erholdte råprodukt kan så eventuelt methyleres i dimethylformamid med methyljodid og natriumhydrid.
Fremgangsmåten ifølge krav 2c) skjer likeledes under betingelser som er vel kjent for fagfolk. Således kan eksempelvis forbindelsene med den generelle formel V i et inert oppløsningsmiddel (dioxan, tetrahydrofuran, glycoldimethylether, etc.) omsettes med 1ithium-diisopropylamid og carbondioxyd. På den annen side er det eksempelvis også mulig å omsette forbindelsene med den generelle-formel i i et inert oppløsningsmiddel (dioxan, tetrahydrofuran, glycoldimethylether, etc.) med kaliumhydrid og klorcarbonsyre-ethylester.
De for disse fremgangsmåtevarianter nødvendige utgangsforbindelser med den generelle formel V kan eksempelvis fremstilles ved fremgangsmåten ifølge krav 1.
De øvrige eventualtrekk ifølge krav 1 eller 2 kan eksempelvis utføres under de betingelser som er beskrevet i DOS 24 31 292.
, I
Fremgangsmåten ifølge krav 3a) er også tidligere kjent.. Den kan utføres på den måte at forbindelsene med formel VI i vandig oppløsning eller suspensjon, eventuelt under tilsetning av polare oppløsningsmidler, som methanol, ethanol, dioxan, tetrahydrofuran, dimethylformamid eller hexamethylfosforsyretriamid, omsettes med et overskudd av hydroxylamin-o-sulfonsyre (1,2 til 5 mol/mol utgangs-forbindelse) ved en reaksjonstemperatur på 20 - 80°G.
De til denne fremgangsmåte nødvendige utgangsforbindelser med den generelle formel VI kan eksempelvis fremstilles fra forbindelser med den generelle formel I hvor X er hydrogen, idet disse eventuelt under tilsetning av dimethylformamid som oppløsnings-middel, oppvarmes med en aminalester, som f.eks. bis-(dimethyl-amino)-t-butyloxy-methan eller med dimethylformamidacetaler, som f.eks. dimethylformamiddimethylacetal, ved 100 til 150°C.
Fremgangsmåten ifølge krav 3b kan utføres under de betingelser som man vanligvis anvender for utbytning av et halogenatom med en cyanogruppe.
Denne reaksjon utføres fortrinnsvis i et protisk oppløsnings-middel (som methanol, ethanol, isopropanol) eller et dipolart, aprotisk oppløsningsmiddel (som dimethylformamid, N-methylacetamid, N-methylpyrrolidon, acetonitril, dimethysulfoxyd eller hexamethylfosforsyretriamid)o Som.alkalimetallcyanid anvendes i denne reaksjon fortrinnsvis natriumcyanid eller kaliumcyanid.
Ved denne omsetning kan man ofte øke utbyttet av fremgangs - måteprodukt når reaksjonen utføres i nærvær av en krone-ether (f.eks. dibenzo~18-krone-6).
Fremstillingen av forbindelsene med den generelle formel VII, som er nødvendig som utgangsforbindelser for fremgangsmåten ifølge krav 3, er beskrevet i de efterfølgende eksempler.
Oxydasjonen av thioforbindelsene til sulfoxydene eller sul-fonene med den generelle formel I skjer ved i og for seg kjente metoder.
Ved denne reaksjon kan man som oxydasjonsmiddel eksempelvis anvende persyrer, som pereddiksyre, perbenzoesyre eller m-klor-perbenzoesyre, hydrogenperoxyd, halogener som klor, brom eller jod, IV - VII-verdige metalloxyder eller -salter, som bly(IV)-oxyd, mangan(IV)-oxyd, krom(VI)-oxyd, cerium(IV)-sulfat, kalium-, kromat, kaliumdikromat, kaliumpermanganat eller oxyderende halogen-forbindelser som natriumperjodat, N-bromsuccinimid, N-klor-succinimid eller natriumhypoklorit„
Hvis man ved denne oxydasjon anvender hydrogenperoxyd eller metalloxyder, eller -salter, er det hensiktsmessig å utføre oxydasjonen i nærvær av syrer. Egnede syrer er mineralsyrer, som saltsyre eller svovelsyre eller lavere carboxylsyrer, som ed.dik-syre eller propionsyre.
Som oppløsningsmiddel kan man ved disse reaksjoner anvende såvel protiske som aprotiske inerte oppløsningsmidler. Egnede, oppløsningsmidler er eksempelvis lavere carboxylsyrer som eddiksyre eller propionsyre, t-alkoholer som t-butanol, ketoner som aceton, methylethylketon eller cyclohexanon, ethere som diethylether, diisopropylether, tetrahydrofuran, dioxan eller glycoldimethylether, hydrocarboner som benzen eller toluen eller klorerte hydrocarboner som methylenklorid, kloroform, carbontetraklorid, tetraklorethan eller klorbenzen. Ved fremstilling av sulfoner med den generelle formel I anvendes fortrinnsvis eddiksyre som oppløs-ningsmiddel. Fremstillingen av sulfoxyder skjer fortrinnsvis i aceton som oppløsningsmiddel.
Den eventuelt påfølgende omsetning av methylsulfinylforbind-elsene med alkalimetallazider skjer ved i og for seg kjente metoder, således eksempelvis ved at forbindelsene i nærvær av syrer som svovelsyre, fosforsyre eller polyfosforsyre, omsettes med natriumazid.
De efterfølgende eksempler tjener til ytterligere å belyse oppfinnelsen.
