In the title molecule, C20H17F2NO, which adopts an E conformation with respect to the imine C=N double bond, the mean planes of the naphthalene ring system and the difluorophenyl ring form a dihedral angle of 85.82 (7)°. An intramolecular C—HN hydrogen bond occurs. In the crystal, weak C—HF hydrogen bonds link the molecules into zigzag chains along [010].
