4-Bromo-2-(cyclopropylmethyl)thiophene (50 mg, 0.23 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 (80 mg, 0.19 mmol) and K2CO3 (105 mg, 0.76 mmol) was taken up in 1,4-dioxane (3 mL) and water (1.5 mL) in a microwave vial. The mixture was degassed by bubbling argon through it for 5 min. PdCl2(dppf).DCM adduct (25 mg, 0.031 mmol) was added, and the reaction was heated in a microwave for 5 min at 100° C. The reaction mixture was concentrated, diluted in DMSO, and purified on a Gilson HPLC(NH4OH buffer). The desired fractions were concentrated, giving 18 mg (22%) of the title compound.
