Ethyl 4-(2,5-di-methyl-phen-yl)-6-methyl-2-sulfanyl--idene-1,2,3,4-tetra-hydro-pyrimidine-5-carboxyl-ate

摘要

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 shallow boat conformation and the 2,5-dimethylphenyl ring is positioned axially. The crystal structure features N—HS, N—HO and C—HO hydrogen bonds, which link the molecules into (101) sheets.
