In the molecule of the title compound, C24H20F2N6O4·C2H5OH, the pyrimidine ring is oriented at dihedral angles of 42.64 (3) and 62.94 (3)° with respect to the benzene rings, while the dihedral angle between the benzene rings is 74.45 (3)°. The pyridine ring adopts an envelope conformation. In the crystal structure, intermolecular N-HO and O-HN hydrogen bonds link the molecules into a two-dimensional network, forming R22(8) ring motifs. - contacts between the pyrimidine and benzene rings [centroid-centroid distances = 3.516 (1) and 3.927 (1) Å] may further stabilize the structure.
