There are two independent molecules in the asymmetric unit of the title compound, C22H14FN3, which differ slightly in the relative orientations of the naphthyl and phenyl groups with respect to the pyridyl ring framework. In one molecule, the naphthyl ring system and the phenyl ring form dihedral of angles 56.50 (2) and 48.23 (3)°, respectively, with the pyridyl ring plane. In the other molecule, the corresponding dihedral angles are 50.01 (2) and 51.1 (3)°, respectively. In the crystal, intermolecular N—H...N hydrogen bonds connect the independent molecules into dimers.
