In the centrosymmetric title compound, C20H24N2O6S2, the N—H and C=O bonds are trans to each other. In the crystal, intermolecular N—H⋯O(S) hydrogen bonds link the molecules into zigzag chains running along the b axis. The O atom involved in the hydrogen bond has a longer S—O bond than the other O atom bonded to S [1.441 (2) versus 1.428 (2) Å].
