Reaction Steps

A mixture of 1,1-dimethylethyl 4-[7-(aminocarbonyl)-5-bromo-1H-indazol-3-yl]-1-piperidinecarboxylate (Intermediate 5) (30 mg, 0.07 mmols), {3-[(methylsulfonyl)amino]phenyl}boronic acid (46 mg, 0.21 mmols), cesium carbonate (150 mg), and Pd(PPh3)4 (10 mg) in dioxane/water (3/1, 4 mL) was heated at 160° C. for 2700 secs. (microwave irradiation). The resulting mixture was concentrated, redissolved in methylene chloride and filtered. The filtrate was concentrated and used in the next step without further purification.
