Reaction Steps

Following the general procedure of Example 66, a mixture of 5-bromo-3-[1-(ethylsulfonyl)-4-piperidinyl]-1H-indazole-7-carbonitrile (Intermediate 10) (61.3 mg, 0.125 mmols), 3,5-difluorophenyl boronic acid (59 mg, 0.375 mmols), potassium carbonate (104 mg, 0.75 mmol), and chloro(di-2-norbonylphosphine)-(2-dimethylaminomethyl-forrocen-1-yl)palladium (15 mg, 0.025 mmol) in dioxane/water (3/1, 4 mL) was reacted. The reaction mixture was concentrated, redissolved in methylene chloride and filtered. The filtrate was concentrated and the residue was purified by using a Gilson semi-preparative HPLC system, eluting with 10% B to 80% B, where A=H2O (0.1% trifluoroacetic acid) and B=CH3CN (0.1% trifluoroacetic acid) pumped at 25 mL/min to give the title compound (15 mg, 33%)
