Procedure

To a 5 mL conical vial was added 2-methoxyquinolin-3-ylboronic acid (Frontier Scientific, 89 mg, 0.437 mmol), potassium phosphate (Aldrich, 285 mg, 1.345 mmol), PdCl2(AmPhos) (23.80 mg, 0.034 mmol), and 1-(6-(5-bromo-1H-indazol-3-yl)pyrazin-2-yl)piperidin-4-amine dihydrochloride salt (Example 1) (150 mg, 0.336 mmol) which was sealed, evacuated and back-filled with N2 3×. Dioxane (2.8 mL) and water (0.6 mL) were added, and the reaction mixture was heated at 150° C. for 30 min with microwave irradiation. After the reaction mixtures were filtered, the crude reaction mixture was concentrated and purified on silica gel (eluent: 0 to 4% MeOH (with 2M NH3) in DCM) to afford the title compound. MS (ESI, pos. ion) m/z: 438 (M+1).
