실험 절차

One part of 1-amino-2-chloro-4-hydroxyanthraquinone, 10 parts of 1,3-dimethyl-2-imidazolidinone, 1.0 part of potassium carbonate and 2.0 parts of N,N-di-n-octyl-m-aminophenol were mixed at room temperature, and then heated to 150° C. While this temperature was maintained, the reaction was conducted for 5 hours. The reaction mixture was cooled, then charged into 100 parts of water, extracted with toluene and thereafter purified through silica gel column chromatography to obtain an anthraquinone compound as coloring matter No. 1 (yield 90%).
