PROCEDURE
实验过程
A suspension of 5-fluoropicolinaldehyde (10.0 g, 79.94 mmol) in MeOH (160 mL) was treated with sodium borohydride (9.073 g, 239.8 mmol) in portions. The mixture was stirred at ambient temperature for 16 hours. The mixture was quenched with water, concentrated under reduced pressure, diluted with water and extracted with EtOAc. The combined organic extracts were dried (phase separator silicone treated filter paper), and concentrated under reduced pressure to give a clear oil, which was triturated with ether. The resulting solid was collected by filtration to afford (5-fluoropyridin-2-yl)methanol (10.15 g, 99% yield).
