Short Communications


The first representative of a new heterocyclic system, 1,4-diphenyl-5H-[1,2,5]triazepino[5,4-a]-benzimidazole, has been synthesized by condensation of ethyl (2-benzoyl-1H-benzimidazol-1-yl)acetate with hydrazine hydrate, followed by thermal heterocyclization of intermediate bis-hydrazone.
