Reaktionsschritte

To a suspension of sodium hydride (60%, 48 mg) in dimethyl sulfoxide (3 mL) was added benzyltriphenylphosphonium chloride (0.47 g), and the mixture was stirred at 65° C. for 1 hour. The reaction mixture was cooled in ice. To the mixture was added 4-benzyloxy-3-formylindole (0.25 g), and the mixture was stirred at 85° C. for 3 hours. The reaction mixture was cooled to room temperature. To the mixture was added water, and the mixture was extracted with ethyl acetate (three times). The extract was washed with water twice, a saturated aqueous sodium hydrogen carbonate solution and brine successively, and dried over anhydrous magnesium sulfate. The solvent was removed under reduced pressure, and the residue was purified by column chromatography on aminopropylated silica gel (eluent: n-hexane/ethyl acetate=3/1) to give the title compound (0.32 g).
