In the title compound, C14H14ClNO2S, the amido H atom orients itself away from both the ortho-methyl groups in the adjacent aromatic ring. The molecule is twisted at the S atom with an C—SO2—NH—C torsion angle of −69.9 (2)°. The two aromatic rings are tilted relative to each other by 31.9 (1)°. In the crystal, the molecules are packed into zigzag chains along the b axis via intermolecular N—H⋯O hydrogen bonds.
