実験手順

Into 6 ml of N,N-dimethylformamide was dissolved 0.23 g of 2-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}phenol. After adding 0.22 g of anhydrous potassium carbonate, 0.13 g of methyl 2-bromopropionate was added at room temperature with stirring and then the mixture was stirred at 80° C. for 3 hours. After cooling the reaction solution to room temperature, the reaction solution was poured into ice-water and extracted with ethyl acetate. The organic layer was washed with saturated aqueous sodium chloride solution, dried over anhydrous magnesium sulfate and concentrated. The residue was subjected to silica-gel column chromatography to give 0.23 g of methyl 2-[2-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}phenoxy]propionate [Compound A-3].
