Procedure

A solution of (2-cyano-benzyl)-carbamic acid tert-butyl ester (35 mg, 0.15 mmol), sodium azide (49 mg, 0.75 mmol), ammonium chloride (40 mg, 0.75 mmol) in dimethylformamide (0.5 ml) was heated to 110° C. for 8 h. After cooling to room temperature, ethyl acetate was added and the resultant solid filtered. Concentration of the filtrate gave [2-(1H-tetrazol-5-yl)-benzyl]-carbamic acid tert-butyl ester; 1H NMR (CD3OD, 400 MHz) δ 7.71(d, 1H, J=7.5 Hz), 7.58 (m, 2H), 7.48 (m, 1H), 4.44 (s, 2H), 1.42 (s, 9H).
