Procedure

When 11.7 g of 1,8-diamino-4,5-dihydroxy-2,7-dibromoanthraquinone (compare Example 350a) are used as the anthraquinone component in Example 415a, then 4.5 g, corresponding to 37% of theory, of 1,8-diamino-4,5-dihydroxy-2-phenoxy-7-bromoanthraquinone are correspondingly obtained. Colour shade on silica gel: blue of Indicator Number 14 (Colour Index Hue Indication Chart).
