Procedure

Following the general procedure of Example 66, a mixture of 5-bromo-3-[1-(ethylsulfonyl)-4-piperidinyl]-1H-indazole-7-carbonitrile (Intermediate 10) (50 mg, 0.102 mmols), 3,4-difluorophenyl boronic acid (48 mg, 0.306 mmols), potassium carbonate (84 mg, 0.612 mmol), and chloro(di-2-norbonylphosphino)-(2-dimethylaminomethyl-ferrocen-1-yl)paladium (3 mg) 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 (11 mg, 24%)
