Versuchsvorschrift

A mixture of 9-benzenesulfonyl-3-bromo-5-hydroxy-9H-dipyrido[2,3-b;4′,3′-d]pyrrole-6-carbonitrile (500 mg, 1.16 mmol), 1-methyl-4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1H-pyrazole (500 mg, 2.40 mmol) and [1,1′-bis(diphenylphosphino) ferrocene]dichloropalladium(II) (200 mg, 0.25 mmol) in 2N aqueous potassium acetate (3.6 mL) and acetonitrile (7.2 mL) was heated under microwave irradiation at 140° C., for 30 minutes. The reaction mixture was allowed to cool to ambient temperature, 1M hydrochloric acid (7.5 mL) was added and the mixture was stirred at room temperature for 1 h. The resulting precipitate was collected by filtration, washed with acetonitrile (5 mL) and left to air dry to afford the title compound as a crude brown solid (500 mg, 99%). LCMS (Method G): RT=3.84 min, M+H+=431.
