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.
一种用于生产化合物的多步骤过程,该化合物的分子式为V:其中R'和R"是1至3个碳原子的烷基,包括或一起;是吡咯烷基、哌啶基、4-甲基哌嗪基或吗啉基;环A和环B未取代,或被来自氟、氯、溴、硝基和三氟甲基的一种或多种取代基取代,该过程包括将式1的化合物的当量与2当量的α-邻苯二甲酰亚胺乙酰卤在惰性有机溶剂中处理,以获得1,3-二氧杂-2-异吲哚乙酸,[[N-(2-苯甲酰基苯基)-1,3-二氧杂-2-异吲哚乙酰胺基]亚甲基]肼II,处理III化合物与三氟乙酸,得到化合物III;将化合物III与惰性有机溶剂中的二烷基亚甲基氯化铵处理,得到2-[3-(二烷基氨基)甲基-5-(邻苯二甲酰基甲基)-4H-1,2,4-三唑-4-基]苯并酮IV,并将IV处理与醇中的肼,得到上述化合物V。还声明了中间体II和IV。1-氨甲基三唑苯二氮杂平(V)化合物用于治疗哺乳动物和鸟类的焦虑和/或抑郁症状。
