Reaction Steps

To a solution of 1-(5-(furan-3-yl)pyridin-2-yl)ethanol (0.075 g, 0.403 mmol) in chloroform (5 ml) was added PBr3 (0.321 g, 1.209 mmol), at 0-5° C., the reaction maintained at the same temperature for 15 min, the reaction was slowly warmed to rt and was maintained at rt for another 2 h. The contents were diluted with ethyl acetate (100 mL), bicarbonate solution (10 mL) was added, the organic layer was separated, the organic layer dried over sodium sulphate and distilled to provide 2-(1-bromoethyl)-5-(furan-3-yl)pyridine (0.075 g, 75% yield). LC-MS m/z calcd for [M+H]+ 253.99. found 254.0.
