Synthesis of 3-Phenyl-1H-[1,4]oxazino[4,3-a]benzimidazol-1-one and Its Transformation into 4-Phenyl-2,5-dihydro-1H-[1,2,5]triazepino[5,4-a]benzimidazol-1-one

Abstract

A synthetic route has been proposed to 3-phenyl-1H-[1,4]oxazino[4,3-a]benzimidazol-1-one, which is the first representative of a new heterocyclic system. The transformation of the title compound to 4-phenyl-2,5-dihydro-1H-[1,2,5]triazepino[5,4-a]benzimidazol-1-one via reaction with hydrazine hydrate has been studied.
