Procedure

Under nitrogen flow, anhydrous THF (1 ml) was combined with Sm (705 mg, 4.7 mmol), and a solution of 1,2-diiodoethane (662 mg, 2.3 mmol) dissolved in anhydrous THF (2 ml) was added dropwise with stirring. The reaction solution was stirred for 30 minutes at room temperature. Thereafter, while cooling with ice, a solution of diiodomethane (723 mg, 2.7 mmol) and 5-(4-chlorobenzyl)-2-trifluoromethylcyclopentanone (Compound (V), (Ra)Xana=H, (Rb)Xbnb=CF3, Ym=4-Cl) (432 mg, 1.6 mmol) dissolved in anhydrous THF (2 ml) was added dropwise, and stirring was continued for 2 hours at room temperature. The reaction solution was poured into a solution mixture of an aqueous solution of NaOH (NaOH (1.1 g) dissolved in 10 ml of water) and THF (10 ml), and stirring was continued for 30 minutes at room temperature. This reaction solution was combined with ice, neutralized with a 1N aqueous solution of hydrochloric acid, and then extracted with hexane. The organic layer was washed with water and saturated brine, and dried over anhydrous sodium sulfate. The solvent was distilled away under reduced pressure. Silica gel chromatography (eluent; hexane: ethyl acetate=70:1) was conducted for purification to obtain the desired substance.
