Reaction Steps

The crude 2,6-dichloro-5-fluoro-4-iodonicotinonitrile (8.0 g, 25.2 mmol), Et3N (3.3 g, 32.8 mmol) and 5-cyclopropyl-1H-pyrazol-3-amine (3.1 g, 25.2 mmol) were placed in ACN (50 ml) and the resulting solution was heated to 80° C. for 24 hours. The reaction was cooled to room temperature, filtered, and the resulting solid was washed with cold ACN, dried, and collected to give the title compound (3.0 g, 29%). MS: Calcd.: 403. Found: [M+H]+ 404.
