Versuchsvorschrift

To a solution of 5-benzyloxy-6-chloro-2-phenylindole (513 mg) in N,N-dimethylformamide (7.7 mL) was added sodium hydride (in oil, 50 to 72%, 92 mg) under cooling with ice under an argon atmosphere, and the mixture was stirred at room temperature for one hour. Then methyl 6-(chloromethyl)pyridine-2-carboxylate (342 mg) was added, and the mixture was stirred at 80° C. for 18 hours. The reaction mixture was allowed to cool to ambient temperature. A saturated aqueous ammonium chloride solution and water were added to the reaction mixture and this resulting mixture was extracted with ethyl acetate. The organic layer was washed successively with water and saturated saline, dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluting solvent: ethyl acetate-hexane) to obtain the title compound (454 mg).
