실험 절차

To a solution of (1-phenyl-1H-1,2,3-triazol-4-yl)methanol, 7, (1.03 g, 5.87 mmol) in CH2Cl2 (50 mL) was added MnO2 (2.05 g, 23.5 mmol). The reaction mixture was stirred for 3 days at room temperature. The reaction mixture was then filtered through Celite® and the resulting filtrate was concentrated in vacuo. The crude material was purified by silica gel chromatography (0-5% methanol/dichloromethane) yielding 0.83 g (82%) of 9: 1H NMR (400 MHz, CDCl3) δ 10.22 (s, 1H), 8.51 (s, 1H), 7.53, (d, J=9.6 Hz, 2H), 7.58-7.49, (m, 3H).
