Procedimiento

A solution containing 6-(6-methylpyrazin-2-yl)-1H-pyrazolo[4,3-c]pyridine (250 mg, 1.18 mmol), 2-bromo-6-iodo-3-methoxypyridine (570 mg, 1.78 mmol), Copper(I) iodide (225 mg, 1.18 mmol), Potassium carbonate (196 mg, 1.42 mmol) and N,N′-Dimethylethylenediamine (0.25 mL, 2.37 mmol) was stirred at 85° C. 4 h. The reaction was filtered through celite and concentrated. The crude product purified by isco column (EtOAc/Hep eluted at 100% EtOAc) to give the desired product 280 mg 59% yield. MS (ESI) m/z: 397.1.
