実験手順

3-(2-Amino-4-chloro-6-fluoro-3-methylphenyl)-1-methyl-6-trifluoromethyl-2,4(1H, 3H)-pyrimidinedione (1.0 g, 2.9 mmol) and triethylamine (0.58 g, 5.7 mmol) were dissolved in ethyl acetate (15 ml) and the solution was slowly added to a solution of triphosgene (0.85 g, 2.9 mmol) in ethyl acetate (15 ml). Solution was heated under reflux for 2 hr and filtered. Solvent was evaporated to afford the title compound as a residue which was used for the next step.
