Reaction Steps

Methyl 5-chloro-2-(3-fluorophenyl)nicotinate 1-oxide (2.9 g, 10 mmol) was stirred in acetonitrile (30 mL) with triethylamine (2.2 mL, 16 mmol) and trimethylsilyl cyanide (3.4 mL, 26 mmol) was added. The mixture was heated at 70° C. for 1 hour. Evaporation and purification by flash column chromatography using ethyl acetate in hexanes (0-20%) gave the desired compound (2.7 g, 90%). LCMS calculated for C14H9ClFN2O2 (M+H)+: m/z=291.1. found: 290.8.
