实验过程

2-Fluoro-5-methylpyridine (CAN 2369-19-9, 50 g, 90 mmol) and sodium cyanide (CAN 143-33-9, 70 g, 1.43 mol) were dissolved in DMSO (200 mL), the mixture was stirred for 3 days at 150° C. The mixture was cooled to room temperature, ice water (200 mL) was added and the product was obtained as red solid (26.5 g, 50%) by filtration and drying; MS (EI): m/e 119.1 [M+H]+.
