Mode opératoire

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-on-carbon, and the mixture was stirred under hydrogen atmosphere at room temperature for 5 hours. After replacing the reaction system by nitrogen, the reaction solution was filtered over celite and 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.
