Description
Fremgangsmåte til fremstilling av lokalanestetisk virksomme N-alkyl-alkyl-piperidin-monokarbonsyreamider og N-alkyl-alkyl-pyrrolidinmonokarbonsyre-amider.
Foreliggende oppfinnelse angår en
fremgangsmåte til fremstilling av N-alkyl-alkyl-piperidinmonokarbonsyreamider og
N-alkyl-alkyl-pyrrolidinmonokarbonsyre-amider med de generelle formler:
I disse formler betegner R, en alkylgruppe, R2 og R,, kan enten hver enkelt
være en alkylgruppe eller den ene av dem
være en alkylgruppe og den annen et
hydrogenatom. Substituentene R2 og R3
kan være plasert på en hvilken som helst
måte i forhold til kullstoffatomene i de
nitrogenholdige ringer. Dette kan oppnåes
ved passende valg av utgang.smaterialer. I
formlene betegner Ar en substituert eller
ikke substituert benzenkjerne. Når benzen-kjernen er substituert er substituentene
valgt blant alkylgrupper, alkoksygrupper,
hydroksylgrupper, klor eller hydrogen og
står i en eller flere av 2-, 4- og 6-stilling-ene.
De ovenfor angitte amider har vist seg
å være særlig gode lokalbedøvelsesmidler.
Ifølge foreliggende oppfinnelse fremstilles disse amider ved at man kobler en
alkylert eller ikke alkylert N-alkylpiperi-dinmonokarbonsyre, eller en alkylert eller
ikke alkylert N-alkylpyrrolidinmonokar-
bonsyre, eller en slik syres anhydrid, ester eller halogenid med anilin eller anilin substituert som foran nevnt, eller med et ami-net tilsvarende isocyanat, og eventuelt al-kylerer det i ringen bundne nitrogen i det erholdte amid.
I det følgende beskrives som eksemp-ler noen utførelsesformer for oppfinnelsen.
Eksempel 1.
Syrekloridet av 5-etylpiperidin-2-kar-bonsyrehydroklorid fremstilles, hva der hensiktsmessig skjer ved hjelp av fosfor-pentaklorid i acetylklorid. Man lar 211 vc-ktsdeler 5-etylpiperidin-2-karbonsyre-klorid-hydroklorid reagere i aceton med 121 vektsdeler 2,6-xylidin. Blandingen oppvarmes i en halv time på vannbad. Acetonet avdestilleres i vakuum, og residuet opp-løses i vann. Den erholdte vandige opp-løsnings pH-verdi innstilles med lut på 5,5. Ikke reagert xylidin fjernes ved ekstrak-sjon med eter. Den vandige oppløsning behandles med kull, og basen utfelles med
lut. Væsken suges fra krystallene, de vaskes
med vann og tørres i vakuum. To deler dietylsulfat tilsettes, og oppløsningen oppvarmes til 100° C i 4 timer. Vann tilsettes,
og overskuddet av dietylsulfat ekstraheres
med eter. Oppløsningen behandles med
kull, og basen som er N-etyl-5-etyl-piperi-din-2-karbonsyre-2,6-xylidid utfelles med
lut. Væsken nutsjes fra basen og den vaskes med vann.
Eksempel 2.
Man lar 197 vektsdeler 6-metylpiperi-din-3-karbonsyrekloridhydroklorid reagere i aceton med 121 vektsdeler 2,6-xylidin. Efter opparbeidelse og alkylering som angitt i eksempel 1 får man N-etyl-6-metyl-piperidin-3-karbonsyre-2,6-xylidid.
Eksempel 3.
Man lar 211 vektsdeler 2,6-dimetyl-piperidin-4-karbonsyrekloridhydroklorid
reagere i aceton med 121 vektsdeler 2-etyl-anilin. Efter opparbeidelse som angitt i
eksempel 1 og alkylering med dimetylsulfat
får man N-metyl-2,6-dimetylpiperidin-4-karbonsyre-2-etylanilid.
Eksempel 4.
Man lar 184 vektsdeler 5-metylpyrroli-din-2-karbonsyrekloridhydroklorid reagere
i aceton med 121 vektsdeler 2,6-xylidid.
Efter opparbeidelse og alkylering som angitt i eksempel 1 får man N-etyl-5-metyl-pyrrolidin-2-karbonsyre-2,6-xylidid.
Eksempel 5.
Man lar 198 vektsdeler 4-etylpyrrolidin
-2-karbonsyrekloridhydroklorid reagere i aceton med 137 vektsdeler 2-etoksyanilin. Efter opparbeidelse som angitt i eksempel 1 og alkylering med normalt-propylbromid
får man N-n-propyl-4-etylpyrrolidin-2-karbonsyre-2-etoksyanilid.
Eksempel 6.
143 vektsdeler 5-metylpiperidin-2-kar-bonsyre oppvarmes sammen med 295 vektsdeler 2,6-dimetyl-fenylisocyanat under kraftig omrøring til en temperatur på 90-110°. Reaksjonen viser seg ved sterk kull-syreutvikling, og dens slutt ved at kullsyre-utviklingen opphører. Overskudd av isocyanat avdestilleres derpå i vakuum. Residuet tilsettes en ekvivalent mengde 10 %'s salt-syre og kokes i 15 minutter hvorpå blandingen avkøles og filtreres. Fra filtratet utfelles 5-metylpiperidin-2-karbonsyre-2,6-xylidid i krystallinsk form med etsalkali.
Efter filtrering og tørring foretas alkylering som angitt i eksempel 1 med dietylsulfat hvorved man får N-etyl-5-metyl-piperidin-2-karbonsyre-2,6-xylidid.
