Reaction Steps
A mixture of 0.08 g of 5-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}-2-(methoxycarbonyl)methoxypyridine [present compound 7-17] and 1 ml of 48% hydrobromic acid was stirred at reflux temperature for 3 hours. The mixture was neutralized with saturated aqueous sodium bicarbonate solution, and extracted with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate, and concentrated to obtain 0.06 g of 5-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}-2-pyridone.
