3-Benzyl-6-methyl-2-sulfanylidene-2,3-di­hydroquinazolin-4(1H)-one

In the title compound, C16H14N2OS, the quinazoline ring system is essentially planar, with a maximum deviation of 0.029 (3) A. The dihedral angle between the quinazoline and benzene rings is 88.4 (2)°. In the crystal, adjacent mol­ecules are connected via pairs of N—H⋯S and C—H⋯O hydrogen bonds, which generate R22(8) and R22(10) graph-set motifs, respectively, resulting in a supra­molecular chain along the a axis.
