N-(4-Acetylphenyl)-4-methoxybenzenesulfonamide

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 anS(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.
