Reaction Steps

To a 0° C. solution of 5-fluoropyridine-3-carbaldehyde (500 mg, 4.0 mmol) in anhydrous methanol (20 mL) was added sodium borohydride (150 mg, 4.0 mmol). The reaction mixture was stirred at room temperature for 3 hours. Saturated ammonium chloride solution (20 mL) was added. The resultant mixture was extracted with EtOAc (3×20 mL). The organic extracts were combined, dried over MgSO4, filtered, evaporated, and dried in vacuo, affording (5-fluoropyridin-3-yl)methanol (430 mg, 85% yield). The product was used without further purification.
