8.7 gm of 1-nitro-6,7,8,9-tetrahydro-5H-benzocycloheptene [J. Am. Chem. Soc., 5820 (9169)] was dissolved into a mixed solvent of 150 ml of acetic anhydride and 50 ml of acetic acid. The mixture was catalytically hydrogenated with the addition of 10 ml of raney nickel. After removing the catalyst by filtration, the reaction mixture was concentrated, the residue was washed with saturated aqueous solution of sodium bicarbonate and saturated brine, and dried over anhydrous sodium sulfate. The product was concentrated to produce 6.17.gm of the title compound.
