Ethyl 4-(4-hydroxyphenyl)-6-methyl-2-oxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate monohydrate

Abstract

There are three formula units in the asymmetric unit of the title compound, C14H16N2O4·H2O. Molecules are linked by N—H...O hydrogen bonds into dimers with the common R22(8) graph-set motif. Between dimers, single N—H...O hydrogen bonds are formed between the other N—H group of each pyrimidine ring and the hydroxyl groups. The water molecules accept O—H...O hydrogen bonds from the hydroxyl groups and donate hydrogen bonds to the ester groups.
