Abstract
The title compound, C15H15NO4S, was obtained by the condensation of 4-aminoacetophenone and 4-methoxybenzenesulfonyl chloride. The dihedral angle between the benzene rings is 86.56 (9)° and the molecule has an approximate V-shaped conformation. The C atom of the methoxy group is roughly coplanar with its attached ring [deviation = 0.177 (3) Å], as is the methyl C atom of the acetyl group with its ring [deviation = 0.065 (2) Å]. An intramolecular C—H⋯O interaction generates an S(6) ring. In the crystal, N—H⋯O and C—H⋯O hydrogen bonds link the molecules into [010] chains. Weak C—H⋯π interactions are also observed.
