Reaction Steps
In a mixed solution consisting of 50 g of 1,2-dibromoethane, 18.5 g of phenol and 100 ml of water was added dropwise 30 ml of water containing therein 7.9 g of sodium hydroxide at a temperature of 130° C. over 30 minutes with stirring, and the reaction solution was further stirred for 6 hours. After completion the reaction, the organic layer was separated from the reaction solution, washed twice with a saturated aqueous potassium carbonate solution, washed twice with water and dried over anhydrous sodium sulfate. The organic layer was separated by filtration and condensed under reduced pressure to give 34.3 g of 2-phenoxyethyl bromide having a boiling point of 105° C. to 107° C. at 6 mmHg in a yield of 85%.
