Reaction Steps

To a 5 mL conical microwave vial was added Pd(dppf)Cl2 (15.53 mg, 0.02 mmol), 1-(6-(5-bromo-1H-indazol-3-yl)pyrazin-2-yl)piperidin-4-amine dihydrochloride salt (Example 1) (71 mg, 0.19 mmol), and 5-(cyclopropylcarbamoyl)-2-fluorophenylboronic acid (46.7 mg, 0.21 mmol), capped, degassed and backfilled with argon (3×). Dioxane (1.9 mL) and 2N Na2CO3 aqueous solution (0.2 mL, 0.48 mmol) were added. The reaction mixture was stirred at 80° C. for 16 h. After cooling to RT, the reaction mixtures were filtered before concentrating under reduced pressure. The crude reaction mixture was purified by preparative HPLC using water with 0.1% NH4OH and ACN with 0.1% NH4OH (Column: Phenomenex Gemini-NX C18 110 A 5 μm, 21×100 mm) to afford the title compound. MS (ESI, pos. ion) m/z: 472 (M+1).
