In the title compound, C24H24N2O3S, the phenyl rings form dihedral angles of 55.65 (11) and 79.60 (11)° with the plane of the thio-phene ring. The mol-ecular conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond, generating an S(6) ring motif. In the crystal, centrosymmetrically related mol-ecules are linked into dimers by two pairs of C-H⋯O inter-actions.
