Versuchsvorschrift
A suspension of copper cyanide (7 g) and 3-chloro-2-iodo-5-nitro-pyridine (7 g) in acetonitrile (200 mL) was heated to 80° C. within 1 hour and stirred at 80° C. for 5 hours. The solvent was evaporated and the residue was filtered in ethyl acetate over silicon dioxide gave 3-chloro-2-cyano-5-nitro-pyridine (4.26 g).
