Reaction Steps
A mixture of 3-nitro-6,7,8,9-tetrahydro-5H-benzocyclohepten-6-one (0.20 g), iron powder (218 mg), ammonium chloride (52 mg), water (1.2 ml) and ethanol (4 ml) was refluxed for 2 hours. After cooling, the insoluble material was filtered off and the filtrate was evaporated in vacuo. To the residue was added ethyl acetate and water. The organic layer was separated and the aqueous layer was extracted with ethyl acetate. The combined organic layer was washed with brine, dried over anhydrous sodium sulfate, and evaporated in vacuo. The residue was purified by column chromatography on silica gel with chloroform as an eluent to give 3-amino-6,7,8,9-tetrahydro-5H-benzocyclohepten-6-one (153 mg).
