Abstract

A process for the preparation of benzodiazepine derivatives, of the formula ** (see formula) ** In which R means hydrogen or alkyl, R1 means hydrogen, halogen or trifluoromethyl and R2 signifies phenyl, halophenyl or pyridyl, And its 4-oxides, characterized by reacting a benzophenone of the general formula ** (see formula) ** In which R, r1 and r2 have the meaning indicated above, with a nitroacetic acid halide, to reduce the nitroacetyl compound obtained from the general formula ** (see formula) ** In which R, r1 and r2 have the meaning indicated above, the corresponding derivative of hydroxylamine or amine and cyclize the product thus obtained.
