実験手順

Under ice-cooling, sodium hydride (60% in oil, 0.48 g, 12.0 mmol) was added to a solution of 3-bromo-2-phenyl-1H-indole (2.72 g, 10.0 mmol) in N,N-dimethylformamide (10 mL) by small portions, and the mixture was stirred under a nitrogen atmosphere at the same temperature for 30 min. 2-Chloroethyl ethyl ether (1.65 mL, 15.0 mmol) was added to the reaction mixture, and the mixture was stirred at 70° C. for 3 hr. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane-25% ethyl acetate/hexane) to give the title compound (2.60 g, yield 76%) as a red oil. MS: m/z 344 (MH+).
