【 摘 要 】

In the title compound, C23H19NO2, an oxazine Mannich base derivative, the oxazine ring has a half-chair conformation. The 2-hy­droxy­naphthalen-1-yl substituent is placed in an axial position. There is an intra­molecular O—H⋯N hydrogen bond, forming an S(6) graph-set motif. In the crystal, mol­ecules are connected by a pair of C—H⋯π inter­actions into an inversion dimer, which is reinforced by another pair of weak C—H⋯π inter­actions. The dimers are linked by a π–π inter­action [centroid-centroid distance = 3.6268 (17) Å], consolidating a column along the a axis. Furthermore, the columns inter­act with each other by a weak C—H⋯π inter­action, generating a three-dimensional network.
