Participants

Reaction Steps

To a solution of 4-(2,6-dimethyl-4-(pyrazin-2-ylthio)phenyl)thiazol-2-amine (11-5, 200 mg, 0.60 mmol) in CH2Cl2 (2.0 mL) was added triethylamine (0.20 mL, 1.9 mmol) followed by 2-fluoroisonicotinic acid (107.7 mg, 1.0 mmol), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (243.9 mg, 1.27 mmol) and hydroxybenzotriazole (172.0 mg, 1.27 mmol). The reaction mixture was stirred at room temperature overnight. The solution was concentrated under reduced pressure and added with hot water. The resultant precipitate was filtered, and dried under vacuum to give N-{4-(2,6-dimethyl-4-(pyrazin-2-ylthio)phenyl)thiazol-2-yl}-2-fluoroisonicotinamide (19, 68.4 mg) as yellow solids in 25% yield: 1H NMR (500 MHz, DMSO-d6) δ 13.10 (s, 1 H), 8.47-8.50 (m, 2 H), 8.36-8.41 (m, 2 H), 7.96 (s, 1 H), 7.80 (s, 1 H), 7.41 (s, 2 H), 7.33 (s, 1 H), 2.13 (s, 6 H); ESI-MS: m/z 438.1 (M+H)+.
