A mixture of 5.0 parts of 5-nitro-1,4,4a,9a-tetrahydroanthraquinone with 3 parts of zinc dust, 10 parts of a 20 wt % aqueous sodium hydroxide and 50 parts of ethanol was refluxed for 2 hours with stirring and, after cooled to 20°C, filtered. The residue was washed with water and poured into a dilute hydrochloric acid to dissolve zinc dust. Crystals were recovered by filration, washed with water and dried under reduced pressure to obtain 3.8 parts of 1-aminoanthraquinone.
