실험 절차

The 2-[2-(3-Nitroindol-1-yl)acetoxymethyl]-2-phenylmalonic acid diethyl ester (100 mg) obtained in Example 9c) was dissolved in tetrahydrofuran (2 mL), ethanol (4 mL) and water (1 mL), and to the solution were added ammonium chloride (57 mg) and reduced iron (60 mg). The mixture was stirred at 100° C. for 2 hours, cooled, and filtered through a Celite pad. The filtrate was concentrated and diluted with ethyl acetate. The extract was washed successively with saturated aqueous sodium bicarbonate, water and saturated brine, dried over sodium sulfate, and concentrated to give the title compound (93 mg).
