Abstract: The asymmetric unit of the title compound, C₁₈H₁₄F₃N₃O₅·H₂O, contains two independent formula units. The two heterocyclic molecules differ in the orientations of the benzoylphenyl group with respect to the tetrahydropyrimidine ring [C-C-C-C torsion angles of 64.5 (3) and 67.1 (3)°]. In both molecules the pyrimidine ring adopts a half-chair conformation. The molecules are linked into a two-dimensional network parallel to (001) by N-HO and O-HO hydrogen bonds.
