To a mixture of 1-prop-2-yn-1-yl-1H-indole-2,3-dione (190 mg, 1.03 mmol), 1,2-dichloro-4-iodobenzene (420 mg, 1.54 mmol), copper(I) iodide (11.0 mg, 0.06 mmol) and triphenylphosphine (40.0 mg, 0.15 mmol) in degassed DMF (24 mL) was added triethyl-amine (307 μL, 2.15 mmol). The reaction was stirred for 5 minutes and Pd(OAc)2 (13.0 mg, 0.06 mmol) was then added. The reaction was stirred at room temperature for 2 days, concentrated in vacuo, dissolved in EtOAc and washed with saturated NaHCO3(aq) (1×). The layers were separated and the aqueous layer was extracted with additional EtOAc (2×).
