In the crystal structure of the title compound, C(22)H(28)N(2)O(6)S(2), the asymmetric unit contains one half mol-ecule with a center of symmetry at the mid-point of the central C-C bond. The conformations of all the N-H, C= O and C-H bonds in the central amide and aliphatic segments are anti to their adjacent bonds. The mol-ecule is bent at the S atom with an C-SO(2)-NH-C(O) torsion angle of -76.4 (3)°. The dihedral angle between the benzene ring and the SO(2)-NH-C(O) segment in the two halves of the mol-ecule is 67.2 (1)°. In the crystal, N-H⋯O(C) inter-molecular hydrogen bonds link the mol-ecules into chains along the b axis.
