In a 250 mL round bottom flask, 2-fluoropyridine-3-carbaldehyde (2.5 g, 20 mmol) was dissolved in anhydrous ethanol (20 mL). The solution was cooled to 0° C. under nitrogen. NaBH4 (1.5 g, 40 mmol) was added in one portion. The mixture was stirred at room temperature for 2 hours and quenched by addition of water (5 mL). Na2SO4 (20 g) was added. After 10 minutes, the mixture was filtered. The filtrate was evaporated to provide (2-fluoropyridin-3-yl)methanol.
