Abstract: The title compound, C10H13ClN2O, was obtained as a by-product in the reaction of 2-chloromethyl-1H-benzimidazole, dimethyl sulfate and toluene to synthesise 2-chloromethyl-1-methylbenzimidazole. The dihedral angle between the benzene ring and the acetamide group is 89.72  (6)° while that between the aromatic ring and the chloracetyl group is 84.40 (4)°. In the crystal, adjacent molecules are linked by pairs of N-H...O hydrogen bonds into inversion dimers.
