Reaction Conditions

Reaction Steps

4.5 g of phenyl 1-amino-4,5,8-trichloroanthraquinone-2-carboxylate and 2 g of anhydrous potassium carbonate are introduced into 100 cc of dimethylformamide, 4 g of 4-methylthiophenol are added, and the mixture is then heated to 80° C. under a gentle stream of nitrogen and is kept at this temperature until the reaction is complete. The reaction mixture is then diluted at 40° C. with 40 cc of water, is allowed to cool completely and is filtered with suction, and the product is washed with a mixture of dimethylformamide and water and then with water. After drying at 60° C., 4.8 g of phenyl 1-amino-4,5,8-tri-(4-methylphenylmercapto)-anthraquinone-2-carboxylate are obtained, corresponding to a yield of 67% of theory.
