✦ Synopsis

In the molecule of the title compound, C~18~H~12~FNO~2~, the oxazine ring is not planar and has a flattened boat conformation The dihedral angle between the benzene ring and the naphthalene system is 78.4 (3)°. In the crystal structure, intermolecular N—H...O hydrogen bonds link the molecules into dimers, which may be effective in the stabilization of the structure.
