Description
Fremgangsmåte for fremstilling av hittil ukjente terapeutisk virksomme benzodiazepinderivater.
Nærværende oppfinnelse vedrører en
fremgangsmåte for fremstilling av 5-fe-nyl-3H-l,4-benzodiazepin-2(1H)-oner. Dis-se er verdifulle terapeutiske midler og kan finne anvendelse som anticonvulsiva, mus-kelrelaxantia og sedativa. De kan admini-streres oralt eller parenteralt i enhver van-lig farmasøytisk form, f. eks. som oppløs-ning, suspensjon, kapsel, tabletter, suppo-sitorier eller lignende.
De ifølge oppfinnelsen fremstillbare
forbindelser tilsvarer den generelle formel
hvor R, betyr hydrogen eller lavere alkyl og R, hydrogen, lavere alkyl, halogen, hydroxy, lavere alkoxy eller trifluormethyl og Ri| og R4 hydrogen, lavere alkyl, halogen, hydroxy, lavere alkoxy, trifluormethyl, ni-tro, amino, lavere alkanoylamino, lavere alkylthio, lavere alkylsulfinyl eller lavere alkylsulfonyl. Fremgangsmåten ifølge oppfinnelsen består i at man omsetter et keton med den generelle formel
hvor R,, R,, R,, og R4 har den samme be-tydning som ovenfor angitt,
med en halogenhydrogensyre, fortrinnsvis bromhydrogensyre, i nærvær av eddiksyre, bringer reaksjonsproduktet på en pH-verdi på minst 7 og isolerer det dannede benzodiazepin.
Behandlingen av et 2-carbobenzoxy-glycylamido-benzo-fenon med en halogenhydrogensyre i nærvær av eddiksyre bevir-ker den selektive spaltning av en av amid-bindingene i carbobenzoxy-glycylamido-kjeden, slik at en glycylamido-forbindelse med den generelle formel
oppstår.
Fortrinnsvis anvender man ved fremgangsmåten ifølge oppfinnelsen bromhydrogensyre som halogenhydrogensyre. An-dre halogenhydrogensyrer, som klorhydro-gensyre, kan imidlertid likeledes anvendes. Reaksjonen kan gjennomføres enten i van-dig eller i vannfritt medium, såvel som enten ved romtemperatur eller temperaturer over eller under romtemperaturen.
Den dannede glycylamido-forbindelse cycliserer etter at man har bragt pH-verdien på minst 7, dvs. minst til nøytralitet.
Cycliseringen inntrer allerede ved henstand ved romtemperatur. En oppvarmning begunstiger dog cycliseringen. De for høy-ning av pH-verdien egnede alkalier kan enten avlede seg fra sterke eller fra svake baser, f. eks. ammoniakk, alkalihydroxyder, som natriumhydroxyd eller kaliumhydr-oxyd. j ordalkalihydroxyder, som kalsium-hydroxyder og lignende.
5-fenyl-3H-l,4-benzodiazepin-2(lH)-oner kan utvinnes direkte fra 2-carboben-zoxyglycylamido-benzofenoner uten isole-ring av 2-glycylamido-benzofenon-mel-lomproduktet, idet det rå mellomprodukt, som inneholder sistnevnte forbindelse, inn-stilles alkalisk.
Utgangsmaterialene for fremgangsmåten ifølge oppfinnelsen dvs. forbindelsene med den foranstående formel II er nye. De kan oppnåes ved innføring av carbobenz-oxyglycyl-resten i de tilsvarende 2-amino-benzofenoner. Egnede midler for innføring av denne rest er forbindelser, som carbobenzoxyglycin, carbobenzoxy-glycinanhy-rlrid og carbobenzoxyglycylhalogenider. Denne reaksjon kan gjennomføres ved romtemperatur eller ved temperaturer over eller under romtemperatur. Fortrinnsvis om-detter man da carbobenzoxyglycin med et ?-aminobenzofenon i nærvær av et N,N'-rUsubstituert carbodiimid. Det som konden-sasionsmiddel anvendte N,N'-disubstituerte carbodiimid kan oppnåes på forskjellige måter. Hvis man anvender egnede substi-tuerte carbodiimider, f. eks. N,N'-dicyclo-hexylcarbodiimid, får man urinstoffderi-vater som biprodukter, som lett kan skilles fra reaksjonsproduktet. Reaksjonen kan gjennomføres f. eks. ved en temperatur mellom 0° og 50, fortrinnsvis ved romtemperatur eller en noe derover liggende temperatur. Fortrinnsvis anvender man et opp-løsningsmiddel for reaksjonen. Som sådant egner seg f. eks. organiske oppløsningcmid-ler, som methylenklorid, kloroform, dioxan, tetrahydrofuran, dimethylformamid, ace-tonitril og lignende eller også vann.
Omdannelsen av 2-amino-benzofenoner til 2-glycylamido-benzofenoner over
innføringen av en carbobenzoxyglycylrest og etterfølgende behandling med en halogenhydrogensyre i nærvær av eddiksyre er <p>n virkningsfull måte for denne overføring,
•om forløper med gode utbytter.
De følgende eksempler anskueliggjør fremgangsmåten ifølge oppfinnelsen. Alle temperaturer er angitt i Celsiusgrader.
Eksempel 1.
En oppløsning av 2,25 g (2-benzoyl-4-trifluormethyl-fenyl-carbamoylmethyl)-carbaminsyre-benzylester i 15 ml 20 pst. bromhydrogensyre i eddiksyre røres i 25
minutter ved romtemperatur. Det erholdte
2-glycylamido-5-trifluormethyl-benzofe-non isoleres ikke. Reaksjonsblandingen til-dettes 200 ml vannfri ether. Man tilsetter derpå vann og avkjøler reaksjonsblandingen i et isbad og innstiller svakt alkalisk med ammoniakk. Det organiske sjikt skilles fra, vaskes med vann, tørkes over natriumsulfat og konsentreres til tørrhet i vakuum. Resten oppvarmes under tilbakeløp i 3 ti-mer i 30 ml pyridin. Etter fjerning av opp-løsningsmidlet i vakuum omkrystalliseres resten fra hexan, hvorved man får 7-trifluormethyl-5-fenyl-3H-l,4-benzodiazepin-2(lH)-on.
Utgangsmaterialet kan fremstilles som følger: Se eksempel 1 i patent nr. 104 964.
Eksempel 2.
i3n oppløsning av 3,0 g (2-benzoyl-4-methoxy-fenylcarbamovlmethyl)-carbaminsyre-benzylester i 30 ml 20 pst. bromhydrogensyre i eddiksyre røres 30 minutter ved romtemperatur. Man tilsetter langsomt 175 ml vannfri ether, hvorpå et gummiaktig bunnfall skiller seg ut. Den ovenstående væske helles fra og resten fordeles mellom vann og ether. Det erholdte 2-glycylamido-5-methoxy-benzofenon isoleres ikke. Etter avkjøling i is nøytraliseres reaksionsblan-h i ngen med ammoniakk. Ethersjiktet skilles 'ra, tørkes over natriumsulfat og bringes
til tørrhet i vakuum. Resten krystalliserer ved henstand. Ved omkrystallisasjon fra benzol/hexan får man 7-methoxy-5-fenyl-3H-l,4-benzodiazepin-2(lH)-on.
Eksempel 3.
En oppløsning av 3,1 g (2-benzoyl-4-klor-fenylcarbamoylmethyl)-carbaminsyre-benzylester i 30 ml 20 pst. bromhydrogensyre i iseddik røres i 45 minutter ved romtemperatur. Etter tilsetning av 175 ml vannfri ether skiller et gummiaktig produkt seg ut. Etter noen minutter dekanteres etheroppløsningen. Det erholdte 5-klor-2-glycylamido-benzofenon isoleres ikke. Man tilsetter 155 ml ether til resten og etter av-kjøling i et isbad tilsettes 10 pst.'ig natron-lut inntil reaksjonsblandingen er alkalisk. Etheroppløsningen skilles fra, vaskes to ganger med vann og tørkes over natriumsulfat. Etter filtrering dampes etheropp-løsningen inn til tørrhet i vakuum. Resten av 7-klor-5-fenyl-3H-l,4-benzodiazepin-2 (lH)-on krystalliserer man fra benzol.
