Versuchsvorschrift

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 (200 mg, 0.434 mmol) in dioxane (3.0 mL) and H2O (1.0 mL) was added 6-bromo-2,3-dihydro-1H-inden-1-one (274 mg, 1.30 mmol), and potassium carbonate (360 mg, 2.60 mmol) in a microwave tube. The reaction mixture was degassed for 5 min before the addition of tetrakis (triphenylphosphosphine) palladium (0) (50 mg, 0.043 mmol). The reaction was then heated in the microwave for 30 min at 160° C. The reaction was then filtered and the solid was dissolved in EtOAc and H2O. The organic layer was separated and concentrated. The crude residue was purified by Gilson Preparatory HPLC to yield 3-[1-(ethylsulfonyl)-4-piperidinyl]-5-(3-oxo-2,3-dihydro-1H-inden-5-yl)-1H-indole-7-carboxamide.
