Procedure

When the process according to Example 190a is carried out and, instead of the anthraquinone component mentioned there, 11.7 g of 1,5-diamino-4,8-dihydroxy-2,6-dibromoanthraquinone, compare Example 348a, are used, then 3.8 g, corresponding to 31% of theory, of 1,5-diamino-4,8-dihydroxy-2-phenoxy-6-bromoanthraquinone are obtained.
