Abstract
The tetrahydroquinazole fused-ring system of the title compound, C16H14N2O2S, is roughly planar (r.m.s. deviation = 0.039 angstrom); the phenyl ring of the benzyl substituent is aligned at 78.1 (1)degrees with respect to the mean plane of the fused-ring system. In the crystal, two molecules are linked by a pair of N-H center dot center dot center dot S hydrogen bonds about a center of inversion, generating a dimer.
