Description
Det er kjent at 1,4-benzodiazepiner med formel
hvor X har ovennevnte betydning, kan oksyderes ved hjelp av alminnelige oksydasjonsmidier, f.eks. CrO-^, til dannelse av en dobbeltbinding i 4-5-stilling.
Hvis imidlertid nitrogenatomet i 1-stillingen er
substituert med en alkylgruppe, f.eks. en metylgruppe, har det ikke hittil lykkedes ved hjelp av vanlige oksydasjonsmidier å
gjennomføre denne oksydasjon for innførelse av nevnte dobbeltbinding,
idet oksydasjonen i slike tilfelle går videre, hvorved det hoved-
sakelig fremkommer 2,3~diokso-forbindelsen (J. Org. Chem.,
30, 1308, 1965).
Det har nå overraskende vist seg at man kan fremstille
forbindelser med den ovenfor angitte generelle formel I, hvis man ifølge oppfinnelsen behandler en forbindelse med den generelle formel
med azodikarboksylsyredietylester, idet det inntrer følgende reaksjon:
Denne reaksjon forløper glatt på kort tid og full-stendig kvantitativt, hvilket er en stor fordel, fordi man derved unngår de rensningsproblemer som ellers er karakteristiske for de foran omtalte oksydasjonsmetoder med vanlige oksydasjonsmidier.
Ifølge en hensiktsmessig utførelsesform for oppfinnelsen oksyderes l-metyl-1,2,4,5-tetrahydro-5~fenyl-3H~7-klor-l,4-benzo-diazepin-2-on til l-metyl-l,2-dihydro-5-fenyl-3H-7-klor-l,4-benzodiazepin-2-on.
De ved fremgangsmåten fremstilte forbindelser, og spesielt den ovenfor nevnte, utmerker seg som det er kjent ved kraftig sedativ og tranquilliserende virkning.
Fremgangsmåten ifølge oppfinnelsen skal forklares nærmere ved hjelp av et utførelseseksempel.
Eksempel.
Til 1,4 g l-metyl-1,2,4,5-tetrahydro-5~fenyl-3H-7-klor-l,4-benzodiazepin-2-on oppløst i 20 ml tørr benzol settes 0,87 g azodikarboksylsyre-dietylester. Blandingen kokes under tilbakeløp i 1 time og hensettes natten over ved værelsetemperatur. De utskilte krystaller av hydrazodikarboksylsyre-dietylester suges fra (0,7 g, smp. 130-133°C). Benzoloppløsningen inndampes i vakuum til tørrhet. Residuet oppløses i 10 ml kokende isopropanol. Ved avkjøling ut-skilles 1,1 g l-metyl-l,2-dihydro-5-fenyl-3H-7-klor-l,4-benzo-diazepin-2-on med smp. 128-130°C.
