Abstract :
A general method for the synthesis of benzimidazole-4-sulfonamides is described. This methodology employs commercially available benzothiadiazole-4-sulfonyl chloride as a benzimidazole equivalent. Reaction with a variety of amines followed by highly chemoselective reductive desulfurization gives intermediate 1,2-phenylenediamines, which may then react with aryl, heteroaryl, and alkyl aldehydes to provide substituted benzimidazole sulfonamides.
