Procedure

4-Cyano-3-(2-methoxyethoxy)aniline (760 mg, 4 mmol) and 2,2-dimethyl-5-methoxymethylene-1,3-dioxane-4,6-dione (1.0 g, 5.4 mmol), (Montatsh. Chem. 1967, 98, 564), in ethanol (20 ml) was heated at reflux for 1 hour. The mixture was allowed to cool and the solid collected by filtration to give 5-((4-cyano-3-(2-methoxyethoxy)anilino)methylene)-2,2-dimethyl-1,3-dioxane-4,6-dione (840 mg, 61%) as an orange solid.
