Versuchsvorschrift

Methyl 2,5-dichloronicotinate 1-oxide (16 g, 72 mmol) was dissolved in acetonitrile (200 mL) with triethylamine (15 mL, 110 mmol) and trimethylsilyl cyanide (24 mL, 180 mmol) was added. The mixture was heated to 70° C. for 30 minutes. Evaporation and purification on silica gel using ethyl acetate in hexanes (0-30%) gave the desired compound (14 g, 82%). LCMS calculated for C8H5Cl2N2O2 (M+H)+: m/z=231.0. found: 230.8.
