2,2-Dimethyl-5-[(pyridin-2-ylamino)methylidene]-1,3-dioxane-4,6-dione

Abstract

In the title compound, C12H12N2O4, the dihedral angle between the pyridine and enamine planes is 3.5 (3)°, while the angle between the dioxanedione (seven atoms) and enamine planes is 4.6 (3)°. The dioxane ring approximates an envelope conformation.
