YieldReaction ConditionsOperation in experiment
6 g With Dess-Martin periodane; In dichloromethane; at 0 - 23℃; for 16h; DMP (27.37g, 64.4 immol) was added portion wise to a stirred solution of (5-fluoro-6-methoxypyridin-3-yl)methanol (6.8g, 43.83mmol) in DCM (l5OmL) at 0C and stirred for 16 h at RT. The RM was filteredthrough celite and washed with DCM (3x5OmL).The filtrate was washed with aq. NaHCO3 (200mL), water (lOOmL), brine(l5OmL), dried(Na2504), filtered, concentrated under reduced pressure to give crude. The crude was purified by CC (silica-gel 60-l20mesh, 0-15% EtOAc in PE) to give 5-fluoro-6- methoxynicotinaldehyde (6.Og, 89%) as a white solid.
With manganese(IV) oxide; In dichloromethane; at 20℃; for 6.5h; To a solution of 0.54 g of (5-fluoro-6-methoxypyridin-3-yl)methanol in 5 mL of dichloromethane, 1.5 g of manganese dioxide was added. The mixture was stirred at room temperature for 3 hours, thereto were then added 0.89 g of manganese dioxide and 4 mL of dichloromethane, and the mixture was stirred for 1 hour. Thereto were further added 1.5 g of manganese dioxide and 2 mL of dichloromethane, and the mixture was stirred at room temperature for 2 hours 30 minutes. After leaving overnight, the insoluble substance was filtered off, and the filtration residue was washed with chloroform. The solvent was distilled off under reduced pressure to obtain 0.48 g of 5-fluoro-6-methoxynicotinaldehyde as a yellow solid. 1H-NMR (CDCl3) delta: 4.13 (3H, s), 7.78 (1H, dd, J = 9.8, 1.8 Hz), 8.42 (1H, d, J = 1.8 Hz), 9.97 (1H, d, J = 2.7 Hz)
