Abstract: 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-HO hydrogen bonds with the motif R22(6). In addition to the C-HO interactions, the crystal structure is also stabilized by C-H interactions.
