실험 절차

3-(1,1-dioxidotetrahydro-2H-thiopyran-4-yl)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-indole-7-carboxamide (0.085 g, 0.203 mmol) and 5-bromo-1H-indazole (0.048 g, 0.244 mmol, 1.2 eq) was dissolved in a 6:1 solution of 1,4 dioxane/water in a 20 mL microwave reaction vessel. Potassium carbonate (0.128, 0.929 mmol, 4.6 eq) was added and the solution was degassed with Argon. PdCl2(dppf) (0.023 g, 0.032 mmol, 0.16 eq) was added and the reaction was heated in a microwave at 100° C. for 20 min. Solution was passed through a StratoSphere SPE PL-Thiol MP SPE column to remove palladium and purified on Gilson preparative HPLC using Acetonitrile/Water with 0.1% TFA. 0.020 g (24%) product obtained.
