Participants

Reaction Steps

To a solution of 4-(2,6-dimethyl-4-(pyrazin-2-ylthio)phenyl)thiazol-2-amine (11-5, 500 mg, 1.6 mmol) in CH2Cl2 (10.0 ml) was added triethylamine (0.7 ml, 4.0 mmol) followed by isonicotinoyl chloride hydrochloride (707.7 mg, 4.8 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}isonicotinamide (11, 392.5 mg) as white solids in 59% yield: 1H NMR (500 MHz, DMSO-d) δ 13.1 (s, 1 H), 8.81 (d, J=5.7 Hz, 2 H), 8.50 (s, 1 H), 8.41 (s, 1 H), 8.36 (s, 1H), 8.00 (d, J=5.7 Hz, 2 H), 7.41 (s, 2 H), 7.30 (s, 1 H), 2.13 (s, 6 H). ESI-MS: m/z 420.2 (M+H)+.
