Reaction Steps

A mixture of 0.19 g of 5-{4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]-2-nitrophenoxy}-4-(methoxycarbonyl)methoxy-2-methylpyrimidine, 5 mg of platinum oxide, 2 ml of ethanol and 2 ml of ethyl acetate was stirred for 1.5 hours at room temperature under hydrogen atmosphere. The reaction system was purged with nitrogen, then, the reaction solution was filtrated through Celite, and the filtrate was concentrated to obtain 0.17 g of 5-{2-amino-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}-4-(methoxycarbonyl)methoxy-2-methylpyrimidine.
