Reaction Steps

3-(2-Amino-4-chloro-6-fluoro-3-methylphenyl)-1-methyl-6-trifluoromethyl-2,4(1H, 3H)-pyrimidinedione (0.5 g, 1.4 mmol) was dissolved in 1,4-dioxane (20 ml) and triethyl amine (0.29 g, 2.9 mmol) and 2-naphthoyl chloride (0.41 g, 2.2 mmol) were added. Solution was heated under reflux for 4 hr and solvent removed under reduced pressure.
