The complete mol-ecule of the title compound, C(17)H(22)N(2)O(4)S(2), is generated by crystallographic twofold symmetry, with one C atom lying on the rotation axis. The dihedral angle between the benzene rings is 44.04 (7)° and the conformation of the central N-C-C-C group is gauche. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds, generating corrugated (010) sheets, and weak C-H⋯O inter-actions consolidate the packing.
