In the molecule of the title compound, C14H10FN3O, the bicyclic quinazoline system is effectively planar, with a mean deviation from planarity of 0.0140 (3) Å. The quinazoline heterocyclic system and the adjacent benzene ring make a dihedral angle of 85.73 (9)°. Two intermolecular N—H...N hydrogen bonds contribute to the stability of the crystal structure. In addition, a weak π–π stacking interaction [centroid–centroid distance = 3.902 (2) Å] is observed.
