실험 절차

A 250 mL reaction tube was charged with benzyl alcohol 1 (1.0 g, 3.6 mmol), MnO2 (4.7 g, 54 mmol) and EtOAc (20 mL). The reaction tube was sealed was heated to 120° C. with stirring for 2 h. The reaction was allowed to cool to rt, then filtered through Celite and washed successively with EtOAc, MeOH, and EtOH. The combine organics were concentrated to give 936 mg (3.4 mmol, 94%) of 2 as an orange solid: 1H NMR (300 MHz, CDCl3) δ 10.01 (s, 1H), 8.64 (d, J=5.5 Hz, 1H), 8.09 (br s, 1H), 7.96 (d, J=2.75 Hz, 1H), 7.37 (d, J=2.48 Hz, 1H), 7.29 (d, J=2.75 Hz, 1H), 7.08 (dd, J=2.47, 5.5 Hz, 1H), 6.94 (d, J=9.35 Hz, 1H), 3.08 (d, J=5.23 Hz, 3H).
