Reaction Steps
A mixture of 5.0 parts of 5-nitro-1,4,4a,9a-tetrahydroanthraquinone with 50 parts of pyridine was stirred at 70° C for 1 hour and then poured into 500 parts of water to precipitate crystals. After cooled to 20°C, the crystals were recovered by filtration, washed with water and dried under reduced pressure to obtain 4.5 parts of 1-hydroxylaminoanthraquinone.
