실험 절차

To a solution of 2-Tetrazol-1-yl-benzamide (1.5 g, 7.9 mmol) in tetrahydrofuran (50 ml) was added (methoxycarbonylsulfamoyl)ammonium hydroxide, inner salt (2.8 g, 11.8 mmol) in three portions over 1.5 h. Water was added and the reaction mixture was extracted with ethyl acetate. The combined organic layers were washed with brine. Drying and solvent evaporation gave 2-Tetrazol-1-yl-benzonitrile; 1H NMR (CDCl3, 400 MHz) δ 9.27 (s, 1H), 7.90 (m, 3H), 7.72 (m, 1H).
