실험 절차
A suspension of indole (8.2 g), potassium bicarbonate (12 g) and copper (I) iodide (2.7 g) in bromobenzene (70 mL) was refluxed for 3 hours under nitrogen atmosphere. To the mixture copper (I) iodide (11 g) was added and the mixture was refluxed for additional 6 hours. The insoluble material was removed by filtration and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=50:1 to 20:1) to provide 8.4 g of the title compound. Yield 62%.
