Versuchsvorschrift

6-Nitro-1-indanone (10.0 g, 56.4 mmol) was dissolved in methanol (200 mL), a 10% palladium-carbon powder (500 mg) was added, and the mixture was stirred at room temperature for 14 hr under a hydrogen atmosphere. To the reaction solution were added dichloromethane and ethyl acetate to dissolve the precipitated crystals, and the catalyst was filtered off. The filtrate was concentrated under reduced pressure, and the residue was washed with methanol to give the title compound (6.71 g, yield 81%).
