Versuchsvorschrift

4-Chloro-3-methoxy-2-bromomethyl-pyridine (4.69 g) and sodium cyanide (5.11 g) are added to ml of a 1/1 mixture of water and ethanol. The reaction is stirred at 60° C. for 3 hours. The ethanol is evaporated and the residue diluted in water and extracted with methylene chloride. The desired product is obtained by chromatography using hexane/ethyl acetate (9/1) as solvent.
