A mixture of [5-(2,6-diethyl-phenyl)-1H-pyrrolo[2,3-c]pyridin-3-yl]-acetonitrile (800 mg, 3.1 mmol), 1-iodo-4-isopropyl-benzene (1.13 g, 4.6 mmol), copper iodide (874 mg, 4.6 mmol), Cs2CO3 (1.50 g, 4.6 mmol) and ethylenediamine (30 μL, 4.6 mmol), and dioxane (100 mL) is heated to 60° C. under nitrogen for 18 h. The mixture is diluted with EtOAc and filtered over a small pad of silica gel. The obtained solution is concentrated under reduced pressure, and the residue is purified by chromatography on silica gel (hexane-EtOAc, 5:1) to afford [5-(2,6-diethyl-phenyl)-1-(4-isopropyl-phenyl)-1H-pyrrolo[2,3-c]pyridin-3-yl]-acetonitrile as colorless oil.
