Reaction Steps
5-bromo-3-(1,1-dioxidotetrahydro-3-thienyl)-1H-indole-7-carboxamide (0.050 g, 0.140 mmol) and 2-thienylboronic acid (0.018 g, 0.140 mmol) was dissolved in a 6:1 solution of 1,4 dioxane/water in a 20 mL microwave reaction vessel. Potassium carbonate (0.097 g, 0.70 mmol) was added and the solution was degassed with Argon. PdCl2(dppf) (0.017 g, 0.024 mmol) was added and the reaction was heated in a microwave at 100° C. for 10 min. The solution was passed through a StratoSpheres SPE PL-Thiol MP SPE column to remove palladium and purified on Gilson preparative HPLC using Acetonitrile/0.1% NH4OH/H20. The desired fractions were concentrated, giving 0.017 g (36%) of the title compound.
