実験手順

Following the general procedure of Example 65, a mixture of 1,1-dimethylethyl 4-[7-(aminocarbonyl)-5-bromo-1H-indazol-3-yl]-1-piperidinecarboxylate (Intermediate 5) (100 mg, 0.24 mmols), 3-pyridinylboronic acid (88.5 mg, 0.72 mmols), potassium carbonate (197 mg), and Pd(PPh3)4 (28 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 (33 mg, 38%)
