Abstract
In the title compound, C15H18N2O2S, the 2,3-dihydro-1-benzothiopyran ring adopts a sofa conformation and the hydantoin ring is twisted with respect to the benzene ring at 78.73 (17)°. In the crystal, pairs of N—H⋯O hydrogen bonds link the molecules into inversion dimers.

The N—C bong length values of N11—C12 = 1.349 (3) Å, N13—C12 = 1.400 (4) Å and N13—C14 = 1.359 (2) Å are comparable with the values reported earlier (Manjunath et al, 2011; Hussein et al, 2014)
The shortened bond length values can be attributed to the π conjugation in the hydantoin ring
