In the title compound, C(15)H(16)N(2)O(6)S(2), the dihedral angle between the benzene rings is 83.2 (3)degrees. The molecular conformation is stabilized by an intramolecular C-H center dot center dot center dot O interaction. In the crystal structure, molecules are linked by N-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds and additional stabilization is provided by weak C-H center dot center dot center dot pi interactions.
