Versuchsvorschrift

First, 0.20 g of 2-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}phenol was dissolved in 2 ml of N,N-dimethylformamide, to which 0.083 g of potassium carbonate was added, and the mixture was stirred at room temperature for 50 minutes. Then, 0.077 g of t-butyl chloroacetate was added, and the mixture was stirred at 40° C. to 60° C. for 2 hours. After left for cooling, ice water was poured into the reaction mixture, and after addition of ethyl acetate and saturated aqueous sodium chloride solution, the mixture was subjected to phase separation. The organic layer was washed with saturated aqueous sodium chloride solution, dried over magnesium sulfate, and then concentrated. The residue was subjected to silica gel column chromatography (eluent: n-hexane/ethyl acetate=6/1) to give 10.39 g of t-butyl [2-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}phenoxy]acetate (compound a-121).
