Procedure

A solution of 2-bromomethyl-benzonitrile (1.0 g, 5.1 mmol) and sodium azide (0.40 g, 6.1 mmol) in dimethylformamide (10 ml) was stirred at room temperature for 2 h. Ethyl acetate was added and the reaction mixture was washed with water and brine. Drying and solvent evaporation gave 2-azidomethyl-benzonitrile; 1H NMR (CDCl3, 400 MHz) δ 7.71 (d, 1H, J=7.7 Hz), 7.64 (m, 1H), 7.53 (d, 1H, J=7.8 Hz), 7.47 (t, 1H, J=7.6 Hz), 4.62 (s, 2H).
