To a solution of 5-methoxymethylene-2,2-dimethyl-[1,3]dioxane-4,6-dione (1.8 g) in acetonitrile (15 ml) was added 1-amino-5-phenylcyclohexen-3-one (2.0 g), and the mixture was stirred at room temperature for 24 hours. The resulting crystals were filtered and washed with acetonitrile to give crystals of 2,2-dimethyl-5-[(3-oxo-5-phenyl-1-cyclohexenylamino)methylene]-[1,3]dioxane-4,6-dione (1.2 g).
