Procedure

To a stirred solution of 2-trifluoromethoxybenzyl bromide (0.95 g, 3.9 mmol) from Step 2 above in DMF (5 mL) was added NaCN (0.21 g, 4.3 mmol). The mixture was stirred at ambient temperature for 14 h and the solvent was removed under reduced pressure. The residue was purified by pressurized silica gel column chromatography using 15% EtOAc-hexanes as eluant to give 2-trifluoromethoxyphenylacetonitrile as a colorless liquid (TLC Rf =0.6 (solvent)).
