반응 단계
1-Amino-4-bromoanthraquinone-2-sulfonic acid and 4-(β-acetylaminoethylamino)aniline-3-sulfonic acid were subjected to Ullmann condensation in the presence of cuprous chloride as a catalyst, followed by hydrolysis of the acetyl group under an acid condition of hydrochloric acid, thereby obtaining an anthraquinone intermediate compound of the following formula (2) in the free acid form. ##STR244##
