Reaction Steps

4-Bromo-7-hydroxy-6-nitroindan-1-one (2.90 g, 10.66 mmol) was dissolved in methanol (53 mL), a 10% palladium-carbon powder (290 mg) was added, and the mixture was stirred at room temperature for 6 hr under a hydrogen atmosphere. The catalyst was filtered off using celite, and the filtrate was concentrated under reduced pressure to give the title compound (2.08 g, yield 80%).
