Abstract
A process for the preparation of benzodiazepine derivatives, characterized in that it consists in condensing intramolecularly a compound of the general formula ** (See formula) ** where R1 represents hydrogen, halogen, trifluoromethyl, nitro, amino, cyano, lower alkyl or lower alkoxy, R2 represents hydrogen or lower alkyl, A represents pyridyl, unsubstituted phenyl or phenyl monosubstituted by halogen, trifluoromethyl, lower alkyl or lower alkoxy and R represents hydrogen, lower alkoxy, aryloxy or amino, and, if desired, in treating with a reducing agent the compound thus obtained.
