Procedure

3-Bromomethyl-benzonitrile (150 mg, 0.76 mmol) was dissolved in DMF (2 ml). KCN (55 mg, 0.84 mmol) was dissolved in the minimum amount of water and was added to the reaction. The resulting solution was stirred at 85° C. overnight. The reaction mixture was allowed to cool to room temperature, EtOAc (5 ml) was added, and the solution was washed with saturated NaHCO3 (4×10 ml). The organic layer was dried (MgSO4), filtered and the solvent removed in vacuo to give the title compound.
