In the title compound, C14H12N2O5S, the conformation of the N—C bond in the C—SO2—NH—C(O) segment has gauche torsions with respect to the S=O bonds. The molecule is twisted at the S atom, the C—S(O2)—NH—C(O) torsion angle being 61.8 (5)°. The dihedral angle between the sulfonyl benzene ring and the —SO2—NH—C—O segment is 86.8 (2)° and that between the sulfonyl and the benzoyl benzene rings is 83.8 (2)°. In the crystal, molecules are linked into zigzag chains along the a axis via N—H⋯O hydrogen bonds.
