Benzodiazepine derivatives of the general formula ##STR1## where R.sub.1 is hydrogen or a hydrocarbon residue of 1-8 carbon atoms, R.sub.2 is hydrogen or lower alkyl and rings A and B are unsubstituted or substituted by nitro, trifluoromethyl, halogen, lower alkyl or lower alkoxy, the nitrogen atom in the 5-position being unsubstituted or substituted by an oxygen atom, useful as muscle relaxants, anticonvulsants, sedatives and tranquilizing agents, and processes for production thereof. Also provided are novel intermediates of the general formula ##STR2## where R.sub.2 has the above meaning, rings A and B are unsubstituted or substituted as above and the nitrogen atom in the 4-position is unsubstituted or substituted by an oxygen atom.
