Abstract: In the title compound, C16H12F4N2O3S, the pyrimidine ring adopts a half-chair conformation; the mean plane formed by the ring atoms excluding the C atom bonded to the thiophen-2-ylcarbonyl group has an r.m.s. deviation of 0.059 Å. The dihedral angle between the benzene and thiophene rings is 62.26 (7)°. The molecular conformation is stabilized by an intramolecular O-HO hydrogen bond, generating an S(6) ring. In the crystal, adjacent molecules are connected via a centrosymmetric R22(6) motif, formed by N-HO hydrogen bonds.
