---|---|---|
85% | With manganese(IV) oxide; In dichloromethane; for 16h;Heating / reflux; | (4-FLUORO-3-METHOXYPHENYL) METHANOL (5. 00G, 0. 03mol) and manganese dioxide (33.4g, 0. 38MOL) were stirred in DICHLOROMETHANE (100ml) under an atmosphere of nitrogen, at gentle reflux for 16 hours. The cooled reaction mixture was then filtered through arbacel and concentrated in vacuo to give the title compound as a white solid (4.18g, 0. 027MOL, 85%). 1H NMR (CDCI3, 400MHZ) 8 : 3.96 (s, 3H), 7.23 (d, 1H), 7.43 (m, 1 H), 7.50 (d, 1 H) 9.91 (s, 1H). Mpt: 61-63C. Analysis found C, 62.18 ; H, 4.54%. C8H7FO2 requires C, 62.34 ; H, 4.58%. |

81% | With chromium trioxide pyridine; In dichloromethane; at 20℃; for 0.5h; | To a solution of (4-fluoro-3-methoxyphenyl) methanol (1.56 g, 10 mmol) in dichloromethane (40 mL) was added chromium trioxide pyridine (4.31 g, 20 mmol). The mixture was stirred at room temperature for 30 min and filtered. The filtrate was poured onto a short silica gel column, and eluted with dichloromethane. The resulting solution was concentrated under vacuum to afford the title compound (1.25 g, 81 %). 1H NMR (CDCl3): δ 9.92 (1H, s), 7.52 (1H, dd, J = 2.0 Hz, 8.4 Hz), 7.47-7.43 (1H, m), 7.26-7.22 (1H, m), 3.96 (3H, s). |
