The suspension of 3-bromo-2-hydroxypyridine (80 mg, 0.46 mmol), 1-methyl-1H-indazol-5-ylboronic acid (121 mg, 0.69 mmol) and sodium carbonate (146 mg, 1.38 mmol) in DMF (2.0 mL) and H2O (0.4 mL) was degassed with N2 for 5 minutes. To the mixture was added bis(triphenylphosphine)palladium (II) dichloride (67 mg, 0.09 mmol), and the resulting mixture was heated at 90° C. for 2 h. The reaction mixture was filtered and purified by reverse phase HPLC (Gemini, 5 to 100% ACN/H2O+0.1% TFA) to give the product. LCMS-ESI+ (m/z): [M+H]+ calcd for C13H12N3O: 226.25; Found: 226.2.
