Procedure

Potassium carbonate (23.8 g) and 2-bromophenol (14.9 g) were mixed with dimethylformamide (150 ml). 2-Bromoethanol (12.9 g) was added and the mixture heated to 50° C. for 18 h. The mixture was cooled and added to water (1500 ml). The product was extracted into diethyl ether (×3) and washed twice with dilute sodium hydroxide solution. Evaporation gave 2-(2-bromophenoxy)ethanol (17.4 g).
