Reaction Steps

0.5 g of sodium hydride (purity: 55%) was added to 50 ml of dimethylformamide, and then 3.8 g of 3-(4-trifluoromethoxyphenyl)-6-(2-chlorophenyl)-2,4(1H,3H)-pyrimidinedione was added to the solution with stirring at 0° C. The resulting solution was stirred at room temperature for 15 minutes, then added dropwise with 1.3 g of chloromethylethyl ether and further stirred at room temperature for 3 hours. The reaction mixture was added into 200 ml of ice water and extracted with 200 ml of ethyl acetate. The organic layer was washed with water and dried, and then the solvent was distilled away under reduced pressure to obtain 3.8 g of a crude product. This crude product was recrystallized from diisopropyl ether to obtain 3.2 g of the objective compound.
