反応手順
10 parts of 1-nitroanthraquinone-2-carboxylic acid and 10 parts of hydroxylamine hydrochloride are suspended at room temperature in 60 parts of methanol and 100 parts of 4 N sodium hydroxide. The mixture is refluxed for 3 hours, then cooled to room temperature, diluted with water and acidified with hydrochloric acid. The mixture is filtered and the filter cake is washed neutral with water and dried, affording 7.6 parts of 1,4-diaminoanthraquinone-2-carboxylic acid.
