Ethyl 4-[3,5-bis(trifluoromethyl)phenyl]-6-methyl-2-oxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate

Abstract

In the title compound, C16H14F6N2O3, the dihydropyrimidinone ring adopts an envelope conformation. In the crystal, molecules are linked by N—H...O and C—H...O hydrogen bonds into a ribbon-like structure along the b axis. In the ribbon, a pair of bifurcated acceptor N—H...O and C—H...O bonds generate an R21(6) ring motif. Adjacent ribbons are linked via C—H...F hydrogen bonds.
