Abstract
In the title compound, C15H12ClF3N4O2, the dihydropyrimidine ring exhibits an envelope conformation. The dihedral angle between the mean planes of the dihydropyrimidine and phenyl rings is 83.94 (6)°. The OCH2CH3 group is disordered over two sites with occupancies of 0.155 (3) and 0.845 (3). The crystal packing is stabilized by intermolecular N—H...N hydrogen bonds.
