In the title compound, C 18 H 21 NO 4 , the molecules form dimers by means of a pair of NÐHÁ Á ÁO hydrogen bonds. The 2(1H)pyridone ring displays a screw±boat conformation.
The title compound, C~27~H~27~N~3~O~2~S, was obtained __via__ a multicomponent reaction using benzaldehyde, ethyl acetoacetate, ammonium acetate and phenyl isothiocyanate. The pyrimidine ring assumes a half-boat conformation. The crystal packing is stabilized by N—H...O and N—H...S hydrogen bonds. T
