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.
新的杂环系统的第一个代表是1,4-二苯基-5 H- [1,2,5]三氮杂环庚烷[5,4- a ]-苯并咪唑,它是通过乙基(2-苯甲酰基-1 H -苯并咪唑-1-基)乙酸盐与水合肼,然后热中间体中间体双-。
