실험 절차

A mixture of 0.24 g of 3-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}-2-(benzyloxycarbonyl)methoxypyridine [present compound 7-82], 10 mg of 10% palladium/carbon and 1 ml of ethyl acetate was stirred for 1.5 hours at room temperature under hydrogen atmosphere. There action system was purged with nitrogen, then, the reaction solution was filtrated through Celite, and the filtrate was concentrated. The residue was subjected to silica gel column chromatography to obtain 0.16 g of 3-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}-2-carboxymethoxypyridine [present compound 7-6].
