Det er allerede kendt, at l-ethyl-6-fluor-l,4-dihy-dro-4-oxo-7-piperazino-quinolin-3-carboxylsyrer har antibak-terielle egenskaber, jfr. J. Med. Chem. 23, 1358 (1980).

hvori R betyder hydrogen, methyl eller ethyl, har en overlegen antibakteriel virkning i forhold til de kendte quino-20 Ion- og azaquinolon-carboxylsyrer.
De her omhandlede forbindelser udviser deres overraskende antibakterielle virkning mod både grampositive og gramnegative bakterier, herunder Pseudomonas aeruginosa.
Det har endvidere vist sig, at l-cyclopropyl-6-fluor-25 -l,4-dihydro-4-oxo-7-piperazino-quinolin-3-carboxylsyrerne

Omsætningen af II med III gennemføres fortrinsvis i et fortyndingsmiddel, såsom dimethyl sul f oxid, N,N-dimethyl-formamid, hexamethylphosphorsyretriamid, sulfolan, vand, en 10 alkohol eller pyridin ved temperaturer på 20-200°C, fortrinsvis 80-180°C. Omsætningen kan gennemføres ved normalt tryk, men også ved forhøjet tryk, især når der er tale om lavtko-gende fortyndingsmidler. I almindelighed arbejdes der ved tryk mellem ca. 1 og ca. 100 bar, fortrinsvis mellem 1 og 15 10 bar.
Ved gennemførelse af fremgangsmåden anvendes der pr. mol carboxylsyre II 1-5 mol alkylpiperazin (ved piperazin 1-15 mol), fortrinsvis 2-3 mol alkylpiperazin (ved piperazin 5-10 mol).
20 De fremstillede 7-piperazino-quinolon-3-carboxyl- syrer I kan eventuelt omdannes til salte med organiske eller uorganiske syrer. Syrer, der er egnede til saltdannelse, er f.eks. hydrogenhalogenidsyrer, såsom saltsyre, hydrogenbromidsyre, hydrogeniodidsyre, svovlsyre, eddikesyre, 25 citronsyre og benzensulfonsyre.
'Hvis der ved omsætningen af II med III f.eks. anvendes 7-chlor-l-cyclopropyl-6-fluor-1,4-dihydro-4-oxo-quinolin--3-carboxylsyre og methylpiperazin som reaktanter, kan reaktionsforløbet gengives ved følgende reaktions-30 skema: 35

Herved acyleres malonsyrediethylester (VII) med IV i nærværelse af magnesiumalkoholat til dannelse af acylmalonesteren VIII (Organicum, 3. opl., 1964, s. 438).
Ved partiel forsæbning og decarboxylering af VIII 5 i vandigt medium med katalytiske mængder p-toluensulfonsyre får man i et godt udbytte aroyleddikesyreethylesteren IX, der med o-myresyretriethylester/acetanhydrid omdannes til 2- (2,4-dichlor-5-fluor-benzoyl)-3-ethoxy-acrylsyreethyl-esteren X. Omsætningen af X med cyclopropylamin i et opløs- 10 ningsmiddel, f.eks. methylenchlorid, alkohol, chloroform, cyclohexan eller toluen, fører ved en let eksoterm reaktion til det ønskede mellemprodukt VI.
Ringslutningsreaktionen VI ——> XX gennemføres i et temperaturområde på ca. 60-280°C, fortrinsvis 80-180°C.
15 Som fortyndingsmidler kan der anvendes dioxan, dimethylsulfoxid, N-methylpyrrolidon, sulfolan, hexamethyl-phosphorsyretriamid og fortrinsvis Ν,Ν-dimethylformamid.
I betragtning som syrebindende middel i dette reaktionstrin kommer kalium-tert.butanolat, butyllithium, 20 lithiumphenyl, phenylmagnesiumbromid, natriummethylat og især natriumhydrid eller kaliumcarbonat. Det kan være fordelagtigt at anvende et overskud af base på 10 mol-%.
Det som udgangsforbindelse til denne syntesevej anvendte 2,4-dichlor-5-fluor-benzoylchlorid IV og den tilsvarende 25 carboxylsyre samt det til fremstillingen af IV nødvendige 3- fluor-4,6-dichlortoluen XI er ikke kendt fra litteraturen.
Det efterfølgende reaktionsskema viser fremstillingen af disse udgangsforbindelser og mellemprodukter, idet der gås ud fra 2,4-dichlor-5-methyl-anilin XII.

Herved diazoteres 2,4-dichlor-5-methylanilin (XII) ved hjælp af NaN02/ og det derved dannede diazoniumsalt omdannes med dimethylamin til triazenet Xlla.
Triazenet Xlla opløses i et overskud af vandfrit HF.
5 Derved spaltes triazenet til 2,4-dichlor-5-methyl-diazonium-fluorid og dimethylamin. Uden mellemisolering spaltes denne opløsning termisk ved 130-140°C under N2~fraspaltning til 3-fluor-4,6-dichlortoluen XI (udbytte 77,7% af det teoretiske).
10 3-Fluor-4,6-dichlortoluen XI chloreres i et temperatur område på 110-160°C under UV-bestråling til dannelse af 2.4- dichlor-5-fluor-l-trichlormethylbenzen XIII.
Ved forsæbning af XIII med 95%'s svovlsyre fås 2.4- dichlor-5-£luor-benzoesyre XV, der med thionylchlorid 15 omdannes til carboxylsyrechloridet IV.
Forbindelserne med formlen I udmærker sig ved en særlig god antibakteriel virkning over for grampositive og gramnegative bakterier, især i forhold til forbindelserne ifølge DE patentansøgning P 30 33 157.8 og DE offentiiggørel-20 sesskrift nr. 28 04 097, som det fremgår af den følgende tabel.
