Versuchsvorschrift

A solution of 3-[1-(ethylsulfonyl)-4-piperidinyl]-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-indole-7-carboxamide (40 mg, 0.084 mmol), [2-(4-bromo-1H-pyrazol-1-yl)ethyl]dimethylamine (27 mg, 0.126 mmol) and sodium carbonate (53 mg, 0.5 mmol) was suspended in dioxane (750 μL) and water (250 μL). This was flushed with argon for 10 min before the addition of tetrakis(triphenylphosphine)palladium(0) (5 mg, 0.004 mmol). The resulting mixture was reacted in a microwave for 20 min at 120° C. then diluted with EtOAc (10 mL). The mixture was filtered through Celite and an aqueous wash was performed. It was then purified by Gilson Preparatory HPLC to give 6 mg of the title compound (15%).
