Versuchsvorschrift

Following the general procedure of Example 65, a mixture of 5-bromo-3-[1-(ethylsulfonyl)-4-piperidinyl]-1H-indazole-7-carboxamide (Intermediate 13) (180 mg, 0.4337 mmols), [3-(hydroxymethyl)phenyl]boronic acid (264 mg, 1.74 mmols), cesium carbonate (282 mg, 0.868 mmol), and Pd(PPh3)4 (22 mg, 0.021 mmol) in dioxane/water (2 mL/0.7 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 (130 mg, 68%)
