In the title compound, C(21)H(24)N(2)O(3)S(2), the three five-membered rings adopt envelope conformations. The dihedral angle between the two aromatic rings is 68.4 (1)°. C-H⋯O inter-actions link the mol-ecules into a chain and the chains are cross-linked via C-H⋯π inter-actions involving the meth-oxy-phenyl ring.
