To a solution of (3-chloropyridin-4-yl)methanol (1.0 g, 7.2 mmol) in anhydrous dichloromethane (35 mL) was added dropwise tribromophosphane (750 uL, 7.9 mmol). The mixture was stirred at room temperature for 5 hours. Dichloromethane was evaporated, and the residue was dried in vacuo, affording 4-(bromomethyl)-3-chloropyridine hydrobromide. The product was used for the next step without further purification.
