A solution of 1-bromohexane (60 g) in acetone (150 ml) is added dropwise to a stirred mixture of 4-bromphenol (71 g) and K2CO3 (120 g) in acetone 600 ml) at room temperature. The stirred mixture is heated under reflux for 43 hrs (i.e. until glc revealed complete reaction). The product is extracted into ether twice, and the combined ethereal extracts are washed with water, 5% NaOH water and dried (MgSO4). The solvent is removed in vacuo and the residue was distilled (bp=100°-110° C. at 0.1 mm Hg) to yield a colourless liquid.
