Procedure

3-Iodopropanol (11.23 g) was added to a mixture of 4-bromo-2-(trifluoromethyl)-phenol (15 g) and potassium carbonate (17.2 g) in acetonitrile (150 ml). The above mixture was refluxed for 4 hours then diluted with ethyl acetate (500 ml) and water (300 ml). Organic layer was separated, dried over magnesium sulphate, solvent removed under reduced pressure to give expected product clean enough for use at the next step (18.6 g).
