Participants

Reaction Steps

To a solution of 3-[1-(ethylsulfonyl)-4-piperidinyl]-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-indole-7-carboxamide (150 mg, 0.325 mmol) in dioxane (0.75 mL) and water (0.25 mL), was added 5-bromo-2,3-dihydro-1H-isoindole hydrochloride (130 mg, 0.651 mmol), and cesium carbonate (636 mg, 1.952 mmol). The reaction mixture was kept under argon for 10 min before addition of tetrakis(tripehnylphosphine)palladium(0) (19 mg, 0.016 mmol). The resultant mixture was heated in a microwave for 20 min at 150° C. Mixture was then purified by HPLC to give 11 mg of the title compound.
