摘要

In the title compound, C23H19NO2, an oxazine Mannich base derivative, the oxazine ring has a half-chair conformation. The 2-hy#173;droxy#173;naphthalen-1-yl substituent is placed in an axial position. There is an intra#173;molecular O#8212;H#8943;N hydrogen bond, forming an S(6) graph-set motif. In the crystal, mol#173;ecules are connected by a pair of C#8212;H#8943;#960; inter#173;actions into an inversion dimer, which is reinforced by another pair of weak C#8212;H#8943;#960; inter#173;actions. The dimers are linked by a #960;#8211;#960; inter#173;action centroid-centroid distance = 3.6268#8197;(17)#8197;#197;, consolidating a column along the a axis. Furthermore, the columns inter#173;act with each other by a weak C#8212;H#8943;#960; inter#173;action, generating a three-dimensional network.
