In the title compound, C14H14F4N2O3S, the central dihydro-pyrimidine ring adopts a sofa conformation with the C atom bearing the 2-fluorobenzene ring displaced by 0.596 (3) Å from the other five atoms. The 2-fluorobenzene ring is positioned axially and bisects the pyrimidine ring with a dihedral angle of 70.92 (8)°. The molecular conformation is stabilized by an intramolecular O - H⋯O hydrogen bond, generating an S(6) ring. The crystal structure features C - H⋯ F, N - H⋯S and N - H⋯O hydrogen bonds, which link the molecules into a three-dimensional network.
