Keyword(s):
The title compound, C16H20N2O2S, crystallizes with two molecules in the asymmetric unit, one of which shows positional disorder of the ethyl side chain over two orientations in a 0.555 (7):0.445 (7) ratio. The hydropyrimidine ring adopts a shallowboatconformation and the 2,5-dimethylphenyl ring is positioned axially. The crystal structure features N—H...S, N—H...O and C—H...O hydrogen bonds, which link the molecules into (10-1) sheets.
