Reaction Steps

To a solution of 3.01 g of 5-[3,5-bis(trifluoromethyl)phenyl]-3-[4-(1-bromoethyl)phenyl]-5-trifluoromethyl-4,5-dihydroisoxazole in 10 mL of N,N-dimethylformamide, 1.26 g of potassium phthalimide was added and the resultant mixture was stirred at 80° C. for 3.5 hours. After the completion of the reaction, the reaction mixture was left to be cooled down to room temperature and 20 mL of water was added to the reaction mixture. The resultant mixture was extracted with ethyl acetate (70 mL×1). The organic phase was washed with water (20 mL×1) and then dehydrated and dried over saturated saline and anhydrous magnesium sulfate in this order and the solvent was distilled off under reduced pressure. The resultant residue was purified by silica gel column chromatography eluting with ethyl acetate-hexane (a gradient from 1:10 to 1:5) to obtain 2.80 g of the objective substance as a colorless resinoid.
