In the title mol-ecule, C 21 H 24 N 2 OS, the five-membered ring is planar with an r.m.s. deviation of 0.0142??. The phenyl rings are inclined to the plane of the di-hydro-imidazolone ring by 60.81?(6) and 79.23?(6)°. In the crystal, inversion dimers are formed by a C—H?O hydrogen bond and a C—H? π (ring) inter-action. Additional C—H?O hydrogen bonds and C—H? π (ring) inter-actions connect these dimers into chains along the c -axis direction.
