Versuchsvorschrift

A solution of 2-cyano-3-chloropyridine (1 g, 7.22 mmol) in 1-methyl-2-pyrrolidinone (25 mL) was treated with potassium fluoride (1.26 g, 21.68 mmol) and heated at reflux for 18 hours. After cooling, the reaction was diluted with ethyl acetate and extracted with water and brine. Silica gel chromatography afforded 442 mg (50%) of 2-cyano-3-fluoropyridine.
