Abstract: The title compound, C₉H₁₄N₂O₂S, belongs to a group of esters of 2-oxo- and 2-thioxo-1,2,3,4-tetrahydropyrimidine-5-carboxylic acids, which exhibit a wide spectrum of biological activities. The conformation of the pyrimidine ring is a distorted boat. In the crystal structure, hydrogen-bonded centrosymmetric dimers are formed via intermolecular N-HS hydrogen bonds. The dimers are linked by intermolecular N-HO hydrogen bonds to form a two-dimensional network.
