実験手順
A mixture of 3-cyanophenol (4.14 g, 34.75 mmol) (Aldrich), sodium azide (2.49 g, 38.23 mmol) (Aldrich) and ammonium chloride (2.05 g, 38.23 mmol) in N,N-dimethylformamide (30 mL) were heated to 160° C. for 18 hours. The reaction mixture was concentrated. The residue was purified by C18 column eluting with acetonitrile-water to give 3-(2H-tetrazol-5-yl)-phenol. (Yield 0.9 g, 16%).
