چکیده
In the title mol-ecule, 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 difluoro-phenyl ring form a dihedral angle of 85.82 (7)°. An intra-molecular C-H⋯N hydrogen bond occurs. In the crystal, weak C-H⋯F hydrogen bonds link the mol-ecules into zigzag chains along [010].
