実験手順
Into 10 ml of methanol was dissolved 0.216 g of ethyl 2-[2-({2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidine-1-yl]phenoxy}methyl)phenoxy]propionate obtained in the above-described Production Example 3; a catalytic amount of sodium methoxide was added under ice-cooling and stirring and the mixture was stirred for 6 hours at room temperature. The reaction solution was poured into IN hydrochloric acid and the mixture was extracted twice with ethyl acetate. The organic layers were combined and washed once with a saturated aqueous sodium chloride solution, dried over magnesium sulfate and then concentrated under reduced pressure to give 0.193 g of methyl 2-[2-({ 2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidine-1-yl]phenoxy}methyl)phenoxy]propionate [Compound 3-1].
