Methyl 2-(4-acetamidobenzenesulfonamido)benzoate

Abstract

The molecule of the title compound, C16H16N2O5S, 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.
