실험 절차

To a mixture of 4-bromo-2-(1H-indol-2-yl)phenol (1.44 g, 5 mmol) and 2-bromoethanol (1.12 g, 9 mmol) in 20 mL of THF was added DBAD (2.07 g, 9 mmol) followed by triphenylphosphine (2.36 g, 9 mmol) in portions at room temperature with stirring. After 1 hour, the reaction was concentrated to near dryness, and purified using flash column chromatography (hexane/EtOAc 30:1) to provide the crude product of 2-(5-bromo-2-(2-bromoethoxy)phenyl)-1H-indole (1.98 g, 100%). MS (M+H)+: 394/396/398.
