Abstract
Procedure for the preparation of benzodiazepine derivatives of the general formula **(See formula)** where R1 represents hydrogen, halogen or nitro and R2 represents hydrogen or methyl, and its 4-deoxy derivatives, characterized by a :) reacting a compound of the general formula **(See formula)** where R1 and R2 have the same meaning as before, while A is a starting group, with hydroxylamine or a respective acid salt; or, b) cyclizing a compound of the general formula **(See formula)** where R1, R2 and A have the same meaning as before, in the presence of a base and, if desired, a compound thus obtained is deoxygenated.
