In the title compound, C31H25NO, the oxazine ring adopts a half-chair conformation. The dihedral angles between the phenyl rings and the naphthyl ring system are 70.89 (8), 37.34 (10) and 9.42 (10)°. The crystal structure is stabilized by an aromatic π–π stacking interaction, with a centroid–centroid distance of 3.879 (3) Å.
