title: Ethyl 6-[4-(dimethyl-amino)phen-yl]-4-hydr-oxy-2-oxo-4-(trifluoro-methyl)-hexa-hydro-pyrimidine-5-carboxyl-ate.
abstract: The title compound, C(16)H(20)F(3)N(3)O(4), was prepared by reaction of 4-(dimethyl-amino)benzaldehyde, ethyl 4,4,4-trifluoro-3-oxo-butanoate and urea. In the title mol-ecule, the pyrimidine ring adopts a half-chair conformation and there is an intra-molecular hydrogen bond (O-H⋯O). The crystal structure is stabilized by two types inter-molecular hydrogen bonds (N-H⋯O and N-H⋯N).
