Mono-N-methylation of 2-(ortho-R1-anilino)-4-(p-R2-phenyl)-3H-1,5-benzodiazepines IV is achieved in moderate yield with sodium hydride in methyl iodide. Reaction of the N-methyl derivatives I with methoxyacetyl chloride gave the compounds II and III. The structure of all products was confirmed by ir, 1H-nmr and mass spectrometry.
