In the title compound, C21H23NO6S, the dihedral angle between the thiopene and benzene rings is 88.66 (6)°. In the crystal, molecules are connected by C—HN and C—HO hydrogen bonds, forming a tape along [10-1]. In addition, C—Hπ and π–π stacking [centroid–centroid distance = 3.879 (2) Å between the thiophene rings] interactions are observed.
