A multistep process for the production of a compound of the formula V: ##SPC1## wherein R' and R" are alkyl of 1 to 3 carbon atoms, inclusive or together ##EQU1## is pyrrolidino, piperidino, 4-methylpiperazino or morpholino; and wherein the rings A and B are unsubstituted, or substituted by one or more substituents selected from the group consisting of fluoro, chloro, bromo, nitro and trifluoromethyl, which comprises treating an equivalent of a compound of formula 1: ##SPC2## Wherein rings A and B are defined as above, with 2 equivalents of an .alpha.-phthalimido acetyl halide in an inert organic solvent to obtain a 1,3-dioxo-2-isoindolineacetic acid, [[N-(2-benzoylphenyl)-1,3-dioxo-2-isoindolineacetamido]methylene]hydrazide II which when treated with trifluoroacetic acid gives compound III; treating compound III with a dialkylmethyleneammonium chloride in an inert organic solvent to obtain a 2-[3-(dialkylamino)methyl-5-(phthalimidomethyl)-4H-1,2,4-triazol-4-yl]benz ophenone IV and treating IV with hydrazine in an alkanol to obtain a compound V above. Also claimed are the intermediates II and IV. The 1-aminomethyltriazolobenzodiazepine compounds (V) are used for treatment of anxieties and/or depressions in mammals and birds.
