Abstract

Process for the manufacture of benzodiazepine derivatives of the general formula ** (See formula) ** wherein R1 and R2 represent hydrogen or lower alkyl and R3 represents hydrogen, halogen, lower alkyl or nitro, as well as acid addition salts of said derivatives, which process comprises reacting a quinazoline derivative of the general formula ** (See formula) ** in which X represents halogen, R4 represents hydrogen or nitro and R2 and R3 have the meaning expressed before, with ammonia or a lower alkylamine, nitrate the resulting compound, if a quinazoline derivative is used in which R4 is hydrogen, and, if desired, transform the reaction product into an acid addition salt .
