In the crystal structure of the title compound, C14H13Cl2NO2S, the conformation of the N—C bond in the C—SO2—NH—C segment has gauche torsions with respect to the S=O bonds. The molecule is bent at the N atom, with an C—SO2—NH—C torsion angle of −54.9 (3)°. The two benzene rings are tilted relative to each other by 82.3 (2)°. The molecules are linked into centrosymmetric R22(8) motifs by N—H⋯O hydrogen bonds and C—H⋯π interactions along .
