Reaction Steps

5-bromo-3-(1,1-dioxidotetrahydro-3-thienyl)-1H-indole-7-carboxamide (0.040 g, 0.112 mmol) and 1-{[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2-thienyl]methyl}hexahydro-1H-azepine (0.055 g, 0.172 mmol) was dissolved in a 6:1 solution of 1,4 dioxane/water in a 20 mL microwave reaction vessel. Potassium carbonate (0.077 g, 0.560 mmol) was added and the solution was degassed with Argon. PdCl2(dppf) (0.014 g, 0.019 mmol) 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% TFA. The desired fractions were concentrated, giving 0.015 g (28%) of the title compound.
