Reaktionsschritte
To a solution of sodium borohydride (454 mg, 12.0 mmol) in anhydrous methanol (15 mL) was added a solution of 3-fluoropyridine-4-carbaldehyde (1.0 g, 8.0 mmol) in anhydrous methanol (5 mL) at 0° C. The mixture was stirred overnight at room temperature. Water was added and extracted 3 times with ethyl acetate. The combined organic phase was washed with brine and dried over sodium sulfate. After evaporation of the solvent, (3-fluoropyridin-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 (d, J=5.7 Hz, 2H), 7.50 (t, J=5.2 Hz, 1H) 8.38-8.43 (m, 2H).
