Procedure

To 4.5 g of ([2-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}phenoxy]methyl)benzene were added 230 ml of ethyl acetate and 0.46 g of 10% palladium/carbon, and the mixture was stirred at room temperature under an atmosphere of hydrogen gas for 5 hours. The gas in the atmosphere on the reaction system was replaced with nitrogen gas, and the reaction mixture was filtered through Celite. The filtrate was concentrated to give 3.57 g of 2-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}phenol.
