Crystal structure of ethyl 6-(chloromethyl)-4-(4-chlorophenyl)-2-oxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate

Abstract

In the title compound, C14H14Cl2N2O3, the chlorophenyl ring makes a dihedral angle of 87.08 (9)° with the tetrahydropyrimidine ring. There is a short intramolecular C—H...O contact present. In the crystal, molecules are linked via pairs of N—H...O hydrogen bonds, forming inversion dimers with an R22(8) ring motif. The dimers are linked via a second pair of N—H...O hydrogen bonds, this time enclosing an R44(20) ring motif, forming ribbons along [100]. The ribbons are linked via C—H...O hydrogen bonds, forming sheets lying parallel to (001). The terminal ethyl group is disordered over two positions with an occupancy ratio of 0.654 (17):0.346 (17).
