4,6-Dichloro-1-methyl-1H-pyrazolo[3,4-b]pyridine 5 (0.5 g, 4.9 mmol) was dissolved in acetonitrile (8 mL) and 2-methoxypyridine-4-boronic acid (0.4 g) and 1 M KOAc (8 mL) were added in a microwave tube. Nitrogen was bubbled through the solution for 5 minutes. 1,1′-Bis(diphenylphosphino)ferrocenepalladium (II) chloride (1.21 g) was added and the resultant mixture was then heated by microwave at 120° C. for 5 minutes. The reaction mixture was concentrated in vacuo and purified by flash chromatography (30% EtOAc in hexane) to provide 4-chloro-6-(2-methoxypyridin-4-yl)-1-methyl-1H-pyrazolo[3,4-b]pyridine (0.37 g).
