Reaction Steps

First, 1.0 g of 1-[4-chloro-6-fluoro-3-hydroxy-2-(2-methyl-2-propenyl)phenyl]-3-methyl-4-trifluoromethyl-1,2,3,6-tetrahydropyrimidine-2,6-dione was dissolved in 15 ml of N,N-dimethylformamide, to which 0.43 g of potassium carbonate and 0.4 ml of methyl bromoacetate were added, and the mixture was stirred at room temperature for 30 minutes. After completion of the reaction, the reaction mixture was poured into water and extracted with diethyl ether. The organic layer was dried and concentrated. The residue was subjected to silica gel chromatography, which afforded 1.0 g of 1-[4-chloro-6-fluoro-3-methoxycarbonylmethyloxy-2-(2-methyl-2-propenyl)phenyl]-3-methyl-4-trifluoromethyl-1,2,3,6-tetrahydropyrimidine-2,6-dione.
