Den foreliggende opfindelse angår en analogifrem-gangsmåde til fremstilling af hidtil ukendte 5H-2,3-ben-zodiazepinderivater eller et farmaceutisk acceptabelt syreadditionssalt deraf.
5 De hidtil ukendte forbindelser, der fremstilles ifølge opfindelsen, har den almene formel • K2 R1 R CH--c .
10 ^ · 4 * R . ·. R .
15 hvor R betyder furyl eller eventuelt med halogen, methyl, Ci_4-alkoxy, hydroxy eller trifluormethyl mono- eller di-substitueret phenyl, R-*- betyder en Ci_4-alkylgruppe, R2 betyder et hydrogenatom eller en C1_4-alkylgruppe, R3 betyder 20 en C^_5-alkoxygruppe og R4 betyder en C1_4-alkoxygruppe, idet dog R3 og R4 ikke begge kan betyde en methoxygruppe, hvis R betyder en 3,4-dimethoxyphenylgruppe, R1 betyder en methylgruppe, og R2 betyder en ethylgruppe.
De hidtil ukendte forbindelser med den almene formel 25 (I) har mere signifikante virkninger på centralnervesystemet end 1-(3,4-dimethoxyphenyl)-4-methyl-5-ethyl-7,8-dimethoxy- . . . ® . ® 5H-2,3-benzodiazepxn ("Tofizopam " eller "Grandaxm ") , den eneste 5H-2,3-benzodiazepinforbindelse, der hidtil er syntetiseret. Syntesen og de biologiske egenskaber af "Gran-. ® 30 daxm " er beskrevet i HU-patentskrift nr. 155.572, US-pa-tentskrift nr. 3.736.315 og CH-patentskrift nr. 519.507.

3 formel (I), hvor R3 er C1_5-alkoxyf og/eller at en fremkommet fri base med den almene formel (I), om ønsket, omdannes til et farmaceutisk acceptabelt syreadditionssalt, eller at et fremkommet salt af et 5H-2,3-benzodiazepinderivat med den 5 almene formel (I) omdannes til den frie base eller til et andet syreadditionssalt.
De farmaceutisk acceptable syreadditionssalte af forbindelserne med den almene formel (I) kan fremstilles ved omsætning af de frie baser med f.eks. salt-, hydrogen-10 bromid-, phosphor-, svovl- eller perchlorsyre. Når en hvilken som helst af de substituenter, der er knyttet til benzodia-zepinringen, indeholder et mere basisk nitrogenatom, kan der også anvendes organiske syrer, såsom eddike-, vin-, mælke-, malein- eller fumarsyre, som saltdannende midler.
15 5H-2,3-Benzodiazepinderivaterne med den almene formel (I) renses almindeligvis forud for saltdannelsestrinet, men de rå baser kan imidlertid også underkastes saltdannelse.
Hvis det er vanskeligt at krystallisere en fri base med den almene formel (I), omdannes den fortrinsvis til et godt 20 krystalliserbart salt, såsom rhodanat eller hydrochlorid, hvorfra basen, om ønsket, kan frigøres i ren tilstand.
Hvis der anvendes et 2-benzopyriliumsalt med den almene formel (III) som udgangsforbindelse, gennemføres omsætningen i nærværelse af et syrebindende middel. Der 25 anvendes bekvemt et overskud af hydrazin eller hydrazinhydrat som syrebindende middel, men alkalimetalhydroxider, -car-bonater, -hydrogencarbonater eller organiske baser, f.eks. pyridin eller triethylamin, kan lige så godt anvendes. Om nødvendigt kan udgangsforbindelseme med de almene formler 30 (II) og (III) omdannes til hinanden forud for deres omsætning med hydrazinreaktanten. Ved en foretrukken udførelsesform sættes hydrazinreaktanten direkte til den fremkomne reaktionsblanding .
