2-Bromoethanol (10.37 g) was added to a mixture of 4-bromo-2-(trifluoro-methyl)phenol (20 g) and potassium carbonate (22.94 g) in Acetonitrile (150 ml). The above reaction mixture was refluxed overnight, then diluted with ethyl acetate (500 ml), water (300 ml) the 0.5M sodium hydroxide (300 ml). Organic layer was separated and dried over magnesium sulphate, solvent removed under reduced pressure to give white solid (19 g), NMR consistent with product. 1H NMR (CDCl3) δ: 7.69 (d, 1H), 7.58 (dd, 1H), 6.91 (d, 1H), 4.15 (t, 2H), 3.97 (t, 2H).
