実験手順: Compound 35-2 (1.23 g) was dissolved in methylene chloride (30 ml), triphenylphosphine (1.75 g) and N-bromosuccinimide (1.17 g) were added under ice-cooling, and the mixture was stirred under ice-cooling for 2 hr, and at room temperature for 12 hr. The reaction mixture was washed with water and saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. Diethyl ether (50 ml) was added, and the precipitated triphenylphosphine oxide was filtered off. The concentrate of the filtrate was purified by silica gel column chromatography (hexane alone) to give the object product (1.30 g) as a colorless oil. cooling cooling for 2 hr The reaction mixture was washed with water and saturated brine dried over anhydrous magnesium sulfate The solvent was evaporated under reduced pressure Diethyl ether (50 ml) was added the precipitated triphenylphosphine oxide was filtered off The concentrate of the filtrate was purified by silica gel column chromatography (hexane alone)

実験手順: Triphenylphosphine (315 mg, 1.20 mmol) was added to a solution of 3-(3,5-dichlorophenyl)-propanol (200 mg, 0.98 mmol) in CH2Cl2 (20 mL). The reaction mixture was cooled to 0° C. and bromine (207 mg, 1.30 mmol) was added dropwise. The reaction was stirred at 0° C. for 1 h and was warmed to room temperature. The reaction was poured into water and the aqueous solution was extracted with CH2Cl2. The organic solution was washed with brine, dried over MgSO4, filtered, and concentrated in vacuo. The product was purified by flash chromatography (hexanes) to afford the title compound (134 mg). 1H NMR (400 MHz, CDCl3) δ 7.21 (m, 1H), 7.08 (m, 2H), 3.37 (t, 2H), 2.74 (t, 2H), 2.13 (m, 2H). was warmed to room temperature the aqueous solution was extracted with CH2Cl2 The organic solution was washed with brine dried over MgSO4 filtered concentrated in vacuo The product was purified by flash chromatography (hexanes)
