Description
Fremgangsmåte for fremstilling av terapeutisk aktive benzodiazepinderivater.
Nærværende oppfinnelse vedrorer en fremgangsmåte for fremstilling av nye 1,5-disubstituerte 1,3-dihydro-2H-1,4-benzodiazepin-2-oner med den generelle formel hvor R^betyr amino, lavere-alkanoyl-amino, lavere alkyliden-amino eller fenyl-lavere alkyliden-amino,
R2hydrogen,
R^fenyl, pyridyl, halogensubstituert fenyl,
R^halogen eller nitro,
og de tilsvarende 4-oksyder og syreaddisjonsforbindelser av disse forbindelser, som innehar basisk karakter.
På samme måte vedrorer betegnelsen "lavere alkanoyl" rester som acetyl osv. Betegnelsen "lavere-alkyliden" vedrorer rester som isopropyliden osv. Betegnelsen "halogen" omfatter alle fire halogenene, dvs. fluor, klor, brom og jod (som substituenter i de aromatiske ringene i forbindelser med formel I er spesielt fluor, klor og.brom foretrukket).
Fremgangsmåten ifdlge oppfinnelsen karakteriseres ved at man omsetter en forbindelse med den generelle formel hvor R^ t R Q og R^har den i f.orme 1 I angitte betydning, eller de tilsvarende 4-oksyder med kloramin og, hvis dnsket, enten acylerer det erholdte reaksjonsprodukt med en lavere alkanoylgruppe eller bringer det samme til omsetning med en forbindelse med den generelle formel
hvor R er en lavere alkyliden- eller en fenyl-lavere-alkyl iden-gruppe.
De forbindelser med formel I som har basisk karakter, danner syreaddisjonssalter med i legemiddelsyntesen anvendbare syrer som f.eks. uorganiske syrer, f.eks. bromhydrogensyre, saltsyre, fosforsyre, svovelsyre osv. og organiske syrer som eddiksyre, ravsyre, maleinsyre, metansulfonsyre, p-toluensulfonsyre osv.
Forbindelser med formel I, hvor R^er en lavere . alkanoylamino-gruppe, lar seg fremstille fra de tilsvarende forbindelser med formel I, hvor R, betyr en aminogruppe, ved alkanoylering med de vanlige lavere alkanoyleringsmidler som f.eks. lavere-alkanoyl-halogenider eller lavere-alkanoyl-anhydrider osv.
Forbindelser med formel I, hvor R, betyr en lavere-alkyliden-amino- eller fenyl-lavere-alkyliden-aminogruppe, lar seg fremstille fra de tilsvarende forbindelser med formel 1, hvor R-^er en aminogruppe, ved omsetning med lavere-alkyl-aldehyder (f.eks. acetaldehyd ) , fenyl-lavere-alkyl-aldehyder , di-lavere-alkyl-ketoner (f.eks. aceton), fenyl-lavere-alkyl-ketoner eller benzaldehyd.
Slike forbindelser med formel I er foretrukket, som bærer substituenten R4i 7-stilling og i hvilke den har betydningen halogen (spesielt foretrukket klor eller brom) eller nitro. Videre er også slike forbindelser med formel I foretrukket, : hvor Rg har betydningen fenyl og halogensubstituert fenyl
(spesielt foretrukket o-fluorfenyl eller.o-klorfenyl). Ganske i
spesielt foretrukket er forbindelser, hvor substituenten R^ 5
når den foreligger i en annen betydning enn fenyl, er et ortho-substituert fenyl eller en a-pyridylrest. Forbindelser med formel I, hvor betyr en amino- eller lavere-alkyliden-aminogruppe, er likeledes spesielt viktige.
De nye forbindelsene som de gjengis ved formel I og gjores til-gjengelige ved nærværende fremgangsmåte, såvel som deres i farmasien anvendbare syreaddisjonssalter, er verdifulle beroligelsesmidler, muskelrelaksantia, sedativa og antikon-vulsiva.
Fremgangsmåteproduktene kan finne anvendelse som legemiddel f.eks. i form av farmasøytiske preparater, som inneholder de eller deres salter i blanding med et for den enterale eller parenterale administrasjon egnet farmasøytisk organisk eller uorganisk inert bære-material.
De folgende eksempler illustrerer oppfinnelsen. Alle tem-peraturene er angitt i °C og alle smeltepunkter er korrigerte.
EKSEMPEL 1
