A solution of 5-bromo-3-iodo-1-methyl-1H-pyrrolo[2,3-b]pyridine (150 mg, 0.445 mmol), 1-methylpiperazine (356.7 mg, 3.56 mmol), copper(I) iodide (84.8 mg, 0.445 mmol), K3PO4 (378 mg, 1.78 mmol), 1,2-ethanediol (138 mg, 2.225 mmol) in isopropyl alcohol (5 mL) in a sealed tubes was heated at 70° C. for 2 days. After cooling to room temperature, the reaction mixture was filtered through celite. The filtrate was concentrated in vacuo. The residue was taken up in EtOAc and the solution was washed with saturated NaHCO3, dried and concentrated. Purification by flash chromatography afforded the title compound. LCMS-ESI+: calc'd for C13H17BrN4 309.1 (M+H+); Found: 309.1 (M+H+).
