Versuchsvorschrift

Following the general procedure of Example 66, a mixture of 5-bromo-3-[1-(ethylsulfonyl)-4-piperidinyl]-1H-indazole-7-carboxamide (Intermediate 13) (30 mg, 0.072 mmols), 3-fluorophenyl boronic acid (30 mg, 0.216 mmols), potassium carbonate (60 mg, 0.433 mmol), and Pd(PPh3)4 (8 mg, 0.0072 mmol) in dioxane (2 mL) and water (1 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 (6.57 mg, 21%)
