摘要：

Molecules of the title compound, C22H20N2O2, are situated on crystallographic centres of symmetry. The oxazinane ring adopts a sofa conformation. Molecules are linked into cyclic centrosymmetric dimers via C-H center dot center dot center dot O hydrogen bonds with the motif R-2(2)(6). In addition to the C-H center dot center dot center dot O interactions, the crystal structure is also stabilized by C-H center dot center dot center dot pi interactions.
