Reaction Steps
A round bottom flask was charged with 3-nitro-5-(trifluoromethyl)picolinonitrile (910 mg, 4.19 mmol) and sulfuric acid (4192 μl, 4.19 mmol), and the mixture was stirred at 60° C. for 16 h. Upon cooling to RT the crude mixture was poured onto ice, and the resulting solids were filtered, washed with water and dried. 3-nitro-5-(trifluoromethyl)picolinamide (850 mg, 3.62 mmol, 86% yield) was isolated as a light yellow solid. LC/MS (ESI+) m/z=236.1 (M+H).
