Methyl 2-(4-acetamido­benzene­sulfon­amido)­benzoate

The mol­ecule of the title compound, C(16)H(16)N(2)O(5)S, has the shape of the letter V but with a small twist; the dihedral angle formed between the benzene rings is 79.66 (9)°. The presence of an intra­molecular N—H⋯O hydrogen bond, leading to an S(6) ring, correlates with the near coplanarity of the carboxyl­ate ester group with the benzene ring to which it is connected. The acetamide residue is slightly twisted out of the plane of its benzene ring [C—C—N—C = 13.1 (3)°]. In the crystal, supra­molecular chains along the a axis are mediated by N—H⋯O hydrogen bonds. These are connected into layers via C—H⋯O inter­actions.
