A mixture of 2-(methanesulfonyloxy)-butyronitrile (204 mg, 1.25 mmol) (prepared following Marco et. al., Tetrahedron, 2000, 56, 2525-31) 2-chloro-3-trifluoromethylphenol (196 mg, 1.0 mmol) and potassium carbonate (172 mg, 1.25 mmol) in acetonitrile (5 ml) was stirred for 1 hour at 95° C. The mixture was shaken between tBuOMe and water and the ethereal phase dried with Na2SO4, filtered over a silicagel pad and evaporated to give as yellowish oil 2-(2-chloro-3-trifluoromethyl-phenoxy)-butyronitrile; 1H-NMR (CDCl3): 1.27 t, 3H, 2.20 m, 2H, 2.40 s, 3H, 4.78 t, 1H, 7.34, d, 1H; 7.39, t, 1H, 7.48 d, 1H.
