Abstract: The title compound, C₁₅H₁₇NO₆, is approximately planar, with dihedral angles of 3.11 (4) and 2.12 (4)° between the connecting aminomethylene unit and the planar part of the dioxane ring, and between the dimethoxybenzyl ring and the aminomethylene group, respectively. The dioxane ring exhibits a half-boat conformation, in which the C atom between the dioxane O atoms is 0.5471 (8) Å out of the plane. The molecule has an intramolecular N-HO hydrogen bond which may stabilize the planar conformation. In the crystal, weak intermolecular C-HO hydrogen-bonding contacts, result in the formation of sheets parallel to the ab plane.
