In the title compound, C(22)H(24)N(2)O(4)S(2), the dihedral angles between the central benzene ring and the pendant rings are 66.96 (13) and 69.37 (13)°. The torsion angles for the C-N-S-C fragments are -68.5 (3) and -72.6 (3)°. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds to generate infinite (001) sheets containing R(4) (4)(28) loops. A weak aromatic π-π stacking contact between one of the terminal benzene rings and its inversion-related partner is also observed [centroid-to-centroid separation = 3.796 (2) Å and slippage = 1.581 Å], as are two possible C-H⋯π contacts.
