Abstract
The title compound, C15H14N2O4, is approximately planar, with a dihedral angle of 6.48 (4)° between the aminomethylene unit and the planar five-atom part of the dioxane ring, and a dihedral angle of 2.40 (4)° between aminomethylene unit and the phenylene ring. The dioxane ring is envelope shaped, with the dimethyl-substituted C atom that represents the flap 0.535 (8) Å out of the plane. The molecule has an intramolecular N—H⋯O hydrogen bond.
