CBr4 (497 mg, 1.5 mmol, Aldrich) was added portionwise to a solution of (5,6-dichloro-pyridin-3-yl)-methanol (178 mg, 1.0 mmol, TCI-US) and PPh3 (393 mg, 1.5 mmol, Aldrich) in CH3CN (3 mL) with stirring at room temperature. The mixture was stirred at room temperature for 30 min, the solvent was removed in vacuo and the residue was purified by silica gel column chromatography, eluting with 10% EtOAc/hexane to give the title compound. MS (ESI, pos. ion) m/z: 242 (M+1).
