実験手順
To a flask was added 41.5 grams (g.) (0.3 mole) of 2-phenoxyethanol, 50 ml of toluene and 3.93 g. of pyridine, then 39.3 g. (0.33 mole) of thionyl chloride dropwise while stirring at room temperature. The exothermic reaction was heated at 50°-60° C. for two hours. After cooling to room temperature, the resulting salt was filtered and washed with methylene chloride. The filtrate was washed several times with aqueous sodium bicarbonate, dried using sodium sulfate, and then concentrated to obtain 39 g. of the 1-chloro-2-phenoxyethane as a yellow oil (83% yield).
