The molecule of the title compound, C₁₅H₁₃NO₂, comprises a non-planar oxazine ring (twisted–boat conformation) fused to a benzene ring, and a benzyl moiety. In the crystal, C—H. . . O hydrogen bonds link the molecules into 010 supramolecular chains, enclosing R ₂ ^2 (9) ring motifs. C—H. . . π interactions and very weak π–π stacking between the benzene rings of adjacent molecules help to consolidate the packing. A Hirshfeld surface analysis revealed that the most important contributions to the crystal packing are from H. . . H (48. 8%), H. . . C/C. . . H (29. 3%) and H. . . O/O. . . H (18. 9%) interactions.
