To a microwave vial was added 2,4-dibromo-1,3-thiazole (0.035 g, 0.143 mmol), 3-(1,1-dioxidotetrahydro-2H-thiopyran-4-yl)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-indole-7-carboxamide (0.060 g, 0.143 mmol) and potassium carbonate (0.059 g, 0.429 mmol) along with 1,4-dioxane (1.073 mL)/water (0.358 mL). The mixture was degassed with nitrogen and Pd(PPh3)4 (0.017 g, 0.014 mmol) was added. The reaction mixture was heated in the microwave under ‘high’ absorption setting for 40 minutes at 150° C. The reaction mixture was filtered through a Thiol SPE cartridge (500 mg) eluting with 1:1 MeOH/DCM (10 mL). The eluent was concentrated under nitrogen and purified by RP-HPLC on an X-Bridge C18 column with Acetonitrile/Water (0.1% NH4OH), giving 3 mg (4.6%) of the title compound.
