Reaction Steps

A mixture of 0.30 g of 3-{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 7-7], 0.06 g of sodium carbonate and 3.0 ml of n-pentanol was stirred for 1.5 hours at 100° C. The reaction solution was cooled to room temperature, then, poured into water, and extracted with ethyl acetate. The organic layer was washed with saturated saline, dried over anhydrous magnesium sulfate, and concentrated. The residue was subjected to silica gel column chromatography to obtain 0.07 g of 3-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}-2-(n-pentyloxycarbonyl)methoxypyridine [present compound 7-50].
