In the title molecule, C20H19NO3S, the dihedral angle between the phenyl rings is 48.93 (18)degrees, and they make dihedral angles of 38.37 (17) and 86.50 (19)degrees with the benzene ring. A weak intramolecular C-H center dot center dot center dot O interaction might stabilize the molecular conformation. In the crystal, weak pi-pi stacking interactions between the benzene rings [centroid-centroid distance = 3.774 (2) angstrom] may help to establish the packing.
