Iodine → 6-methyl-3-[5-(1-methyl-1H-pyrazol-4-yl)-1H-pyrrolo[2,3-b]pyridin-3-ylsulfanyl]-[1,2,4]triazolo[4,3-b]pyridazine

Reaction Steps

To a solution of 5-(1-methyl-1H-pyrazol-4-yl)-1H-pyrrolo[2,3-b]pyridine (28 mg, 0.141 mmol) and 6-methyl-[1,2,4]triazolo[4,3-b]pyridazine-3-thiol (35.3 mg, 0.212 mmol) in DMF (700 μL) was added iodine (72 μL, 0.283 mmol). The reaction mixture was stirred at room temperature for 3 hours. The reaction mixture was then filtered and purified by mass-triggered HPLC (5-95% CH3CN/H2O, 0.1% HCOOH modifier) to provide 5.7 mg of 6-methyl-3-[5-(1-methyl-1H-pyrazol-4-yl)-1H-pyrrolo[2,3-b]pyridin-3-ylsulfanyl]-[1,2,4]triazolo[4,3-b]pyridazine (11% yield).
