実験手順: Compound 25-1 (1.00 g) was dissolved in methylene chloride (100 ml), triphenylphosphine (1.71 g) and N-bromosuccinimide (1.15 g) were added under ice-cooling, and the mixture was stirred under ice-cooling for 5 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 (970 mg) as a colorless oil. cooling cooling for 5 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: 3-(3-Chlorophenyl)propionic acid (5.00 g) was dissolved in tetrahydrofuran (100 ml), a tetrahydrofuran-borane.tetrahydrofuran solution (1 mol/l, 34.5 ml) was added dropwise to the mixture under ice-cooling, and the mixture was stirred under ice-cooling for 30 min, and further at room temperature for 15 hr. To the reaction mixture was added water, 1 mol/l aqueous hydrochloric acid solution was added, and the mixture was extracted with ethyl acetate, washed with water, saturated aqueous sodium hydrogen carbonate solution and saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure to give the object product (3.48 g) as a colorless oil. cooling cooling for 30 min was added the mixture was extracted with ethyl acetate washed with water, saturated aqueous sodium hydrogen carbonate solution and saturated brine dried over anhydrous magnesium sulfate The solvent was evaporated under reduced pressure

実験手順: A solution of 3-(3-chloro-phenyl)-propan-1-ol (12.54 g, 73.6 mmol) and N,N′-carbonyl diimidazole (13.12 g, 81 mmol) in CH3CN was stirred at room temperature for 1 h. Allyl bromide (53.43 g, 442 mmol) was added and the reaction was heated at reflux for 24 h. The reaction was cooled to room temperature and brine and EtOAc were added. The aqueous solution was extracted with EtOAc and the organic solution was dried (MgSO4), filtered, and concentrated. Flash chromatography provided the title compound in about 85% yield. 1H NMR (400 MHz, CDCl3) δ 7.30–7.09 (m, 4H), 3.38 (t, 2H), 2.76 (t, 2H), 2.15 (t, 2H). the reaction was heated at reflux for 24 h The aqueous solution was extracted with EtOAc the organic solution was dried (MgSO4) filtered concentrated

実験手順: A slurry of lithium aluminum hydride (2.08 g, 54.7 mmol) in THF (100 mL) was cooled to −78° C. A solution of 3-chlorocinnamic acid (5.00 g, 27.4 mmol) in THF (25 mL) was added dropwise. The cold bath was removed and the mixture was warmed to room temperature. After 6 h, the reaction was quenched by addition of sodium sulfate decahydrate and the mixture was stirred overnight. The solids were removed by filtration with the aid of EtOAc and the organic solution was washed with brine, dried over MgSO4, filtered, and concentrated in vacuo to yield 3-(3-chloro-phenyl)-propan-1-ol (5.17 g) as an oil. 1H NMR (400 MHz, CDCl3) δ 7.30–7.07 (m, 4H), 5.06 (bs, 1H), 3.67 (m, 2H), 2.69 (m, 2H), 1.89 (m, 2H).
