반응 단계
A solution of 5-cyclopropyl-1H-pyrazol-3-amine (1.9 g, 16.0 mmol) in CH3CN (20 ml) was added dropwise to a solution of 2,6-dichloro-5-fluoronicotinonitrile (3.0 g, 16.0 mmol) and triethylamine (2.1 g, 20.0 mmol) in CH3CN (80 ml) at 25° C. The resulting solution was then heated to 82° C. for 18 hrs, and then cooled to 25° C., at which point the product precipitated from solution. The resulting solid was filtered, and washed with CH3CN (100 ml) to give the title compound (3.2 g, 73%). MS: Calcd.: 277. Found: [M+H]+ 278.
