实验步骤: Under a nitrogen atmosphere, a solution of 8.0 grams (0.048 mole) of 3-(4-methoxyphenyl)propanol and 7.9 grams (0.053 mole) of sodium iodide in 50 mL of acetone was stirred, and 5.7 mL (0.053 mole) of 1-chloroethyl chloroformate was slowly added. Upon completion of addition, the reaction mixture was heated to reflux where it was stirred for four hours. After this time the reaction mixture was cooled, and 50 mL of toluene was added. The acetone was removed by distillation after which the reaction mixture was heated for one hour at reflux in the toluene. The reaction mixture was then cooled and poured into 300 mL of water. The mixture was extracted with 200 mL of diethyl ether. The ether extract was washed with 100 mL of an aqueous 5% sodium thiosulfate solution and then with water. The organic layer was dried with magnesium sulfate and filtered. The filtrate was concentrated under reduced pressure to a residual oil, and the oil was dissolved in methylene chloride and filtered through a pad of silica gel. The filtrate was concentrated under reduced pressure to a residual oil. The oil was subjected to column chromatography on silica gel. Elution was accomplished with 40:1 petroleum ether and diethyl ether. The appropriate fractions were combined and concentrated under reduced pressure, yielding 4.3 grams of 3-(4-methoxyphenyl)propyl iodide. The NMR spectrum was consistent with the proposed structure.

实验步骤: Methanesulfonyl chloride (31 mL) was added dropwise to a solution of 3-(4-methoxyphenyl)-1-propanol (50 g) and triethylamine (56 mL) in dichloromethane (800 mL) at 0° C. The resulting mixture was stirred overnight at room temperature. After washing with water, 2% hydrochloric acid and 4% aqueous sodium bicarbonate, the organic solution was dried over sodium sulfate and rotoevaporated to yield crude 3-(4-methoxyphenyl)-1-propyl methanesulfonate as a colourless solid (ca. 83 g). This product and sodium iodide (75 g) in acetone (800 mL) were heated at reflux in the dark for 20 hours. After cooling to room temperature, the reaction mixture was poured into n-hexane/EtOAc/water 1:1:1 (1.5 L) under stirring. The organic layer was washed with water, diluted aqueous sodium metabisulfite and 4% aqueous sodium bicarbonate, then dried (Na2SO4) and concentrated under reduced pressure. The residue was purified by passing it through a short pad of silica gel (eluting with n-hexane/EtOAc 95:5). The title compound was obtained as a pale yellow solid (75 g). at reflux in the dark for 20 hours The organic layer was washed with water, diluted aqueous sodium metabisulfite and 4% aqueous sodium bicarbonate dried (Na2SO4) concentrated under reduced pressure The residue was purified
