A solution of (6-(difluoromethoxy)pyridin-3-yl)methanol (246 mg; 1.41 mmol) in anh. DCM (10 ml) was treated at rt with CBr4 (467 mg; 1.41 mmol), and with triphenylphosphine (369 mg; 1.41 mmol). The resulting mixture was further stirred at rt, under nitrogen, for 15 h. Concentration to dryness under reduced pressure, and subsequent purification by FC (DCM) afforded 5-(bromomethyl)-2-(difluoromethoxy)pyridine as an orange oil which was directly used for the next reaction.
