Reaktionsschritte
2 g of 2,6-dichloro-3-chloromethyl-pyridine in 8 ml of ethanol at ambient temperature was treated with 0.57 g of NaCN. The resulting brown suspension was refluxed for 2 h. Ethanol was removed by evaporation under reduced pressure and the residue was taken-up in water and ethyl acetate. The aqueous layer was washed twice with ethyl acetate. The organic phases were combined, dried over anhydrous sodium sulphate, filtered and concentrated. 2.05 g of crude 2,6-dichloro-pyridin-3-yl)-acetonitrile was obtained as brown solid which was used in the next step without further purification. 1H-NMR (CDCl3): 7.86 ppm (d, 1H), 7.38 ppm (d, 1H), 3.84 ppm (s, 2H).
