Procedure

4-Bromophenol (2 g, 0.0116 mol) in acetone (40 ml) was treated with potassium carbonate (1.91 g, 1.2 equivalents) and benzyl bromide (1.44 ml, 1.05 equivalents). The reaction was refluxed under nitrogen. After 5-6 hours of reflux, the reaction was cooled to room temperature and diluted with an equal volume of ethyl acetate. This was diluted further with water and the organic layer was separated, dried over magnesium sulfate and evaporated to dryness to afford a white fluffy powder. Yield=2.36 g (73%).
