A process for the production of compounds of the formula III: ##SPC1## wherein ring A is unsubstituted or substituted by fluoro, chloro, bromo, trifluoromethyl, or nitro, and wherein Ar is phenyl, o-chlorophenyl, o-fluorophenyl, or 2-pyridyl, is claimed in which the starting compound is the corresponding 1-methyl-6-substituted-4H-s-triazolo[4,3-a][1,4]-benzodiazepine. Compound III is converted to compoud IV or V, the corresponding 1-(2-aminoethyl)-6-substituted-4H-s-triazolo[4,3-a][1,4]benzodiazepines, which are known antidepressant and anti-anxiety agents.
生产III式化合物的方法:##SPC1##其中环A未取代或被氟、氯、溴、三氟甲基或硝基取代,Ar为苯基、邻氯苯基、邻氟苯基或2-吡啶基,所述方法中所述起始化合物为相应的1-甲基-6-取代-4H-s-三唑并[4,3-a][1,4]-苯二氮杂环己烷。化合物III转化为化合物IV或V,即相应的1-(2-氨基乙基)-6-取代-4H-s-三唑并[4,3-a][1,4]苯二氮杂环己烷,这些化合物是已知的抗抑郁和抗焦虑药物。
