Reaction Steps

To a solution of (5-bromo-pyridin-3-yl)-methanol (0.5 g, 2.68 mmol) in DCM (10 mL) was added thionyl chloride (0.5 mL). The resulting solution was stirred at room temperature for 2 h. After this time, the reaction mixture was quenched with water and extracted into DCM. The organic extracts were washed with brine filtered and concentrated under reduced pressure to give 3-bromo-5-chloromethyl-pyridine (0.45 g, 82%), which was used in the next step without further purification.
