N-(4-Acetyl-phen-yl)-4-meth-oxy-benzene-sulfonamide

The title compound, C15H15NO4S, was obtained by the condensation of 4-amino-aceto-phenone and 4-meth-oxy-benzene-sulfonyl chloride. The dihedral angle between the benzene rings is 86.56 (9)° and the mol-ecule has an approximate V-shaped conformation. The C atom of the meth-oxy 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 intra-molecular C-H⋯O inter-action generates an S(6) ring. In the crystal, N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into [010] chains. Weak C-H⋯π inter-actions are also observed.
