The H2O2 –PCl5 reagent system has been found to be an efficient reactive reagent for the one pot conversion of 2- mercaptobenzimidazole to 2-benzimidazolesulfonyl chloride with high purity. 2-Benzimidazolesulfonyl chloride on reaction with aromatic amines in the same pot results in the formation of corresponding new2-benzimidazolesulfonamides derivatives in excellent yields and in short reaction time
