Reaction Steps
5-Bromo-3-(1,1-dioxidotetrahydro-2H-thiopyran-3-yl)-1H-indole-7-carboxamide (0.050, 0.135 mol) and 2-furanylboronic acid (0.020, 0.175 mol) was dissolved in a 6:1 solution of 1,4 dioxane (3 L)/water (0.5 L) in a 20 L microwave reaction vessel. Potassium carbonate (0.093, 0.673 mol) was added and the solution was degassed with Nitrogen. PdCl2(dppf)2 (0.017, 0.023 mol) was added and the reaction was heated in a microwave at 100° C. for 20 min. The 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% NH4OH. The desired fractions were concentrated, giving 0.018 g (37%) of the title compound.
