实验步骤: A mixture of 0.74 g of 2-chloro-4-sec-butoxyphenol, 0.50 g of p-ethylbenzyl alcohol, 1.00 g of triphenylphosphine, 0.65 g of diethylazadicarboxylate and 100 mg of tetrahydrofuran was stirred at room temperatur for 48 hours. The reaction mixture was concentrated, and 50 ml of diethyl ether was added thereto. The precipitates were removed by filtration, and the filtrate was concentrated. The residue was subjected to silica gel chromatography to give 0.71 g of 1-sec-butoxy-3-chloro-4-(4-ethylbenzyloxy)-benzene. Yield, 60%. nD22.6 1.5529. The reaction mixture was concentrated 50 ml of diethyl ether was added The precipitates were removed by filtration the filtrate was concentrated

实验步骤: A mixture of 4-ethylbenzyl alcohol (2.72 g, 20 mmol, purchased from Aldrich) and 50 ml of 47% hydrobromic acid (purchased from Wako Junyaku Kogyo) was stirred vigorously for 30 minutes at room temperature. The reaction mixture was extracted with hexane to give 3.98 g of 4-ethylbenzyl bromide as a colorless oil. Then to a hot solution (50° C.) of sodium cyanide (1.96 g, 40 mmol) in 20 ml of dimethyl sulfoxide was added the above 3.98 g of 4-ethylbenzyl bromide and the mixture was stirred for 3 hours at ambient temperature. To the resultant reaction mass was added water and extracted with hexane. The solvent was removed to give 2.70 g (yield: 93.1%) of 4-ethylphenylacetonitrile as a pale yellow oil. The reaction mixture was extracted with hexane
