Synthesis and biological activity of 5-phenyl-1,3,4-benzotriazepines. 25. Synthesis of (1,2,4)triazolo(4,3-a)(1,3,4)benzotriazepines and related tricyclics

Some title compounds can be obtained conveniently by dehydration of 2-acylhydrazino- or by dehydrogenation of 2-(2-methylenhydrazino)- or by elimination of aniline from 2-phenyl(thio)semicarbazido-1,3,4-benzotriazepines. The direct cyclization of 2-hydraz

Method for preparing 6-phenyl-triazolo or imidazolo-(1,3,4)-benzotriazepines and the novel intermediates used therewith

Novel triazolo- or imidazo-benzotriazepines are prepared from 1,3,4-benzotriazepine-2-thiones which in turn are prepared from a 2-aminobenzophenone.
