Participants

Reaction Steps

To a solution of 0.21 g of 4-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}-3-hydroxy-5-methylpyrazole in 1.0 ml of N,N-dimethylformamide were added 0.10 g of methyl bromoacetate and 0.20 g of potassium carbonate, and the mixture was stirred for 3 hours at room temperature. Dilute hydrochloric acid was poured into this reaction solution, and extracted with ethyl acetate. The organic layer was washed with saturated saline, dried over anhydrous magnesium sulfate. This solution was subjected to silica gel column chromatography to obtain 0.06 g of 3-(methoxycarbonyl)methoxy-4-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}-5-methylpyrazole [present compound 5-17].
