Description
Verfahren zur Herstellung eines Nicotinsäurederivates Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung eines Nicotinsäurederivates. Im Schweizer. Patent Nr. 480 341 wird ein Verfahren zur Herstellung gewisser Nicotinsäu red erivate beschrie ben, die der Formel EMI1.1 entsprechen, worin die Substituenten R, die gleich oder verschieden sein können, Trifluormethyl, Halogen oder niederes Alkyl, R1 Hydroxyl, niederes Alkoxy, Diniederalkylaminoniederalkoxy, Amino, Niederalkylamino oder Diniederalkylamino und n eine ganze Zahl von 1 bis 3 bedeuten; ferner wird die Herstellung von pharmazeutisch annehmbaren Salzen dieser Verbindungen beschrieben. Seit der Einreichung des diesem Patent entsprechenden Gesuches wurden weitere Untersuchungen ausgeführt, um neue Verbindungen und ein neues Salz derselben herzustellen. Die erfindungsgemäss erhältlichen Verbindungen sind physiologisch wirksam und daher auf pharmazeutischem Gebiet brauchbar. Es wurde gefunden, dass sie besonders vorteilhaft als entzündungshemmende Mittel, nicht süchtigmachende Analgetika und Diuretika bei Warmblütern sind. Die bereits beschriebenen Nicotinsäureester reagieren mit unsymmetrisch disubstituierten Hydrazinen unter Bildung von Nicotinsäuresalzen der Formel EMI1.2 worin R3, R4 und Rs niederes Alkyl oder Aryl bedeuten oder Ra und R4 zusammen mit dem Stickstoff Pyrrolidino, Piperidino, Morpholino, 4-Niederalkylpiperazino, 4-(3-Hydroxyniederalkyl)-piperazino oder Hydroxypiperidino bedeuten. Die Behandlung von Methyl-4-( ,cc,,x-trifluor-m-to- luidino)-nicotinat der Formel IX mit unsymmetrischem Dimethylhyd razin unter Verwendung eines Überschusses des Hydrazins als Lösungsmittel oder in Gegenwart eines inerten Lösungsmittels liefert das Hydraziniumsalz der Formel X EMI1.3 Die Umsetzung der verschiedenen 4-substituierten Nicotinsäureester, die unter A aufgeführt sind, mit den unter B aufgeführten unsymmetrisch substituierten Hydrazinen mittels des oben beschriebenen Verfahrens liefert in ähnlicher Weise die gewünschte Hydraziniumsalze, die unter C aufgeführt sind: : A B c Methyl-4-(ααα-trifluor-m- unsym-Diphenylhydrazin 1-Methyl-1,1-diphenylhydrazinium-4-(α,α,α-trifluor- -toluidino)-nicotinat -m-toluidino)-nicotinat Methyl-4-(s -trifluor-m- 1 -Methyl- 1 -phenylhydrazin 1,1 -Dimethyl- 1 -phenylhydrazinium-4-(x, -trifluof - -toluidino)-nicotinat -m-toluidino)-nicotinat Butyl-4-(α,α,α-trifluor-m- 1-Aminopyrrolidin 1-Amiino-1-butypyrrolidinium-4-(α,α,α-trifluor-m- -toluidino)-nicotinat -toluidino)-nicotinat Methyl-4-(α,α,α-trifluor-m- 1-Aminopiperidin 1-Amino-1-methylpiperidinium-4-(α,α,α-trifluor-m -toluidino)-nicotinat -TOLUID -toluidino)-nicotinat Methyl-4-(p-chlor-α,α,α ;-trifluor- 1-Aminornorpholin 1-Amino-1-methylmorpholinium-4-(p-chlor-α,α,α -m-touidino)-nicotinat -trifluor-,-toluidino)-nicotinat Methyl-4-(α,α,α-trifluor-m- 1-Amino-4-methylpiperazin 1-Amino-1,4-dimethylpiperazinium-4-(α,α,α-trifluor -toluidino)-nicotinat -m-toluidino)-nicotinat -toluidino)-nicotinat Methyl-4-α,α,α-trifluor-m- 1-Amino-3-hydroxy- 1-Amino-3-hydroxy-1-methylpipcridinium-4-(α,α,α -toluidino)-nicotinat piperidin -trifluor-m-touidino)-nicotinat Methyl-4-(α,α,α-trifluor-m- 1-Amino-4-(ss-hydroxy- 1-Amino-4-(ss-hydroxyäthyl)-1-methylpiperazinium-4 -toluidino)-nicotinat äthyl)-piperazin -(α,α,α-trifluor-m-toluidino)-nicotinat Beispiel Herstellung von 1,1,1-Trimethylhydrazinium-4 Eine Lösung von 2,2 g Methyl-4-(α,α ;,α-trifluor-m- -toluidino)-nicotinat in 15 cm unsymmetrischem Dimethylhydrazin wird über Nacht zum Rückfluss erhitzt. Nach der Verdampfung des Lösungsmittels wird der Rückstand aus einem Gemisch von dichlormcthan und Äther kristallisiert, wobei er 2,3 g 1,1,1-Trimethylhydra zinium-4-(α,α,α-trifluor-m-toluidino)-nicotinat in Form weisser Nadeln vom Schmelzpunkt 118 bis l210C ergibt.
