Participants

Reaction Steps

To a solution of sodium borohydride (198 mg, 5.2 mmol) in anhydrous methanol (8 mL) was added a solution of 3,5-difluoropyridine-4-carbaldehyde (0.5 g, 3.5 mmol) in anhydrous methanol (2 mL) at 0° C. The mixture was stirred for 6 hours at room temperature. Water was added, and the mixture was extracted 3 times with ethyl acetate. The organic phase was washed with brine and dried over sodium sulfate. After evaporation of the solvent, (3,5-difluoropyridin-4-yl)methanol was obtained and used in the next step without purification; 1H NMR (400 MHz, CDCl3): δ 2.25 (bs, 1H), 4.85 (s, 2H), 8.36 (s, 2H).
