Abstract: The title compound, C₂₂H₂₁N₃O₄S₂, is the product of the nucleophilic attack on a tosyl chloride by 2-amino-1-methylbenzimidazole. The compound contains two tosyl groups, one directly attached to an imidazole ring nitrogen and the other to the exocyclic N atom. The exocyclic N atom is bonded to the imidazole ring through a double bond [1.297 (3) Å]. The compound was also characterized by ¹H NMR spectroscopy.
