In the title compound, C14H12ClNO3S, the conformation of the N—H bond in the C—SO2—NH—C(O) segment is anti to the C=O bond. The dihedral angle between the sulfonyl benzene ring and the —SO2—NH—C—O segment is 89.4 (1)° and that between the sulfonyl and benzoyl benzene rings is 89.1 (2)°. The crystal structure features inversion-related dimers linked by pairs of N—H⋯O hydrogen bonds.
