Ethyl 6-methyl-2-oxo-4-phenyl-1,2,3,4-tetrahydropyrimidine-5-carboxylate

Abstract

The title compound, C14H16N2O3, belongs to a group of esters of 2-oxo- and 1,2,3,4-tetra-hydro-pyrimidine-5-carboxylic acids, which exhibit a wide spectrum of biological activities. The dihydro-pyrimidine ring adopts a screw-boat conformation. The crystal packing is stabilized by strong N - H⋯O and weak C - H⋯O inter-molecular hydrogen bonds. An intra-molecular C - H⋯O hydrogen bond is also present.
