3-Methyl-2-(methyl-sulfan-yl)-5,5-diphenyl-3,5-di-hydro-4 H -imidazol-4-one.

In the title mol-ecule, C 17 H 16 N 2 OS, the di-hydro-imidazolone ring is slightly puckered and the methyl-sulfanyl group is nearly coplanar with it. In the crystal, two sets of C-H⋯O hydrogen bonds form corrugated layers of mol-ecules parallel to the ac plane. The layers pack with normal van der Waals contacts between them.
