5-bromo-3-[(1,1-dioxidotetrahydro-3-thienyl)methyl]-1H-indole-7-carboxamide (40 mg, 0.108 mmol), phenylboronic acid (19.71 mg, 0.162 mmol, 1.5 eq), PdCl2(dppf) (7.88 mg, 10.77 μmol, 0.1 eq), potassium carbonate (44.7 mg, 0.323 mmol, 3 eq) were diluted in a mixture of 1,4-dioxane (3 mL) and water (1 mL), in a 2-5 mL biotage microwave reaction tube. The mixture was degassed by bubbling nitrogen through for 5 minutes and was then heated in a microwave at high absorption for 15 minutes at 120° C. The reaction was filtered through a thiol SPE cartridge (polymer labs) and was concentrated and purified by Gilson HPLC with trifluoroacetic acid buffer. The desired product fractions were combined and concentrated in an EZ2 Genevac evaporator, giving 35.3 mg (84%) of the title compound.
