A capped vial was charged with 4-chloro-6-bromoquinoline (500 mg, 2.06 mmol), 4-methyl-4H-[1,2,4]triazole-3-thiol (238 mg, 2.06 mmol), potassium carbonate (427 mg, 3.09 mmol), and DMF (5 mL). The reaction mixture was stirred at 60° C. for 18 h then at 90° C. for another 24 h, and cooled to room temperature. The reaction mixture was poured onto water (50 mL), and the resulting precipitate was filtered, washed with water and dried in a vacuum oven at 70° C. overnight to provide 600 mg of 6-bromo-4-(4-methyl-4H-[1,2,4]triazol-3-ylsulfanyl)-quinoline as a white solid (91% yield): 1H NMR (DMSO-d6) δ 3.63 (s, 3H), 6.90 (d, 1H), 8.02 (m, 2H), 8.40 (d, 1H), 8.74 (d, 1H), 8.92 (s, 1H); MS (m/z) 321, 323 [M+H]+.
