Procedure

N-(6-Bromo-1-ethyl-1H-indazol-4-yl)-6-methyl-2-pyridinecarboxamide (50 mg, 0.14 mmol), 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-indole (available from Frontier Scientific, 38 mg, 0.17 mmol), Pd(dppf)Cl2 (23 mg), aqueous sodium carbonate (2M, 0.272 ml) and 1,4-dioxane (2 ml) were combined and heated at 150° C. for 10 mins under microwave conditions. The reaction was extracted into DCM (2×20 ml) and the combined organic layers were evaporated to dryness, before purification by Mass Directed Automated Preparative HPLC (Method B). Pure fractions were evaporated to give the title compound (25 mg).
