Reaction Steps

A mixture of 4-nitroxanthen-9-one 2k (4.5 g, 18.7 mmol) and 10% palladium on carbon (200 mg) in ethanol (70 mL) was hydrogenated (hydrogen pressure: 55 psi) for 16 h. The catalyst was removed via filtration and the solvent was evaporated to yield 3.5 g (89%) of title compound 4-aminoxanthen-9-one 3k.
