Reaction Steps

To a solution of potassium carbonate (4.46 g, 32 mmol) in water (20 ml) was added pyridine-4-yl-hydrazine×2HCl (1.47 g, 8 mmol) and the mixture was cooled to 10° C. 2,3-Dichloropropionitrile (1.0 g, 8 mmol) was added dropwise at that temperature. Subsequently, the mixture was stirred at 45° C. for 3 h and at ambient temperature overnight. The reaction mixture was extracted with dichloromethane, the organic phases were combined, washed with brine, dried and the solvent was evaporated. Silica gel chromatography using a heptane/ethyl acetate gradient yielded the amine as yellow solid (80 mg, 6%).
