Abstract

Abstract A procedure has been developed for the synthesis of bis (arylcarbonylamino-1 H- benzimidazol-5-yl) ethers by reaction of the corresponding substituted benzoyl chloride with sodium cyanamide, followed by treatment of the resulting N-cyanobenzamide with 4-(3, 4- diaminophenoxy) benzene-1, 2-diamine in acid medium.
