Reaction Steps
A mixture of 5.0 parts of 5-nitro-2,3-dimethyl-1,4,4a,9a-tetrahydroanthraquinone with 50 parts of water, 50 parts of methylcellosolve and 0.05 parts of potassium carbonate was stirred at 60°C for 1 hour, then cooled to 20°C and filtered to recover crystals. The crystals were washed with water and dried under reduced pressure to obtain 4.5 parts of 5-hydroxylamino-2,3-dimethylanthraquinone.
