Reaction Steps

To a solution of (5-fluoropyridin-3-yl)methanol (430 mg, 3.4 mmol) in anhydrous dichloromethane (30 mL) was added dropwise phosphorus tribromide (650 μL, 6.8 mmol). The mixture was stirred at room temperature overnight. Dichloromethane was evaporated. The residue was dried in vacuo, affording 3-(bromomethyl)-5-fluoropyridine hydrobromide. The product was used without further purification.
