반응 단계
1-Amino-2-carboxy-4-bromoanthraquinone (6.9 parts) and 4-(4'-β-hydroxyethylsulfonylphenoxy)thiophenol (6.5 parts) were allowed to react with each other at 100° to 120° C. in 0-dichlorobenzene in the presence of cuprous chloride and potassium carbonate. Thereafter, methanol was added to the reaction mixture to deposit solids, which were collected on a filter, washed throughly with methanol and water and then dried at 80° C. The resulting product was subjected to sulfonation and esterification simultaneously at 20° to 40° C. in 14% oleum. Thereafter, ice was added thereto, the solids deposited were collected on a filter, thereby obtaining an anthraquinone compound of the following formula (free acid form). ##STR383##
