실험 절차

1-(Phenylsulfonyl)-6-(4,4,6,6-tetramethyl-1,3,2-dioxaborinan-2-yl)-1H-indazol-4-amine (1.5 g, 3.63 mmol), 5-bromo-1-(phenylsulfonyl)-1H-pyrazolo[3,4-b]pyridine (1.350 g, 3.99 mmol), Pd(dppf)Cl2 (0.531 g, 0.726 mmol) and tripotassium phosphate (2.311 g, 10.89 mmol) were divided between 2 microwave vials and dissolved in 1,4-dioxane (18 mL) and Water (6 mL); 9 ml dioxane and 3 ml water in each. Each vial was heated to 100° C. for 10 min in the microwave. Solvent was removed in vacuo and the residue was partitioned between DCM (100 ml) and water (100 ml). The organic layer was collected using a hydrophobic frit and the solvent was removed in vacuo. The residue was taken up in DCM (4 ml) and added to the top of 2×70 g silica SPE cartridges. These were subsequently eluted with 0-100% EtOAc/DCM over 40 mins. The product-containing fractions were combined to give the title compound as a pale yellow solid (581 mg).
