| Reactant | 4,8-Diamino-2,6-dibromo-1,5-dihydroxyanthracene-9,10-dione | HCID 13668123 | — |
| Product | 4,8-Diamino-2-bromo-1,5-dihydroxy-6-phenoxyanthracene-9,10-dione | HCID 20188044 | — |
Reaction Steps
When 11.7 g of 1,5-diamino-4,8-dihydroxy-3,7-dibromoanthraquinone, compared Example 349a, are used as the anthraquinone component in Example 415a, then 3.9 g, corresponding to 32% of theory, of 1,5-diamino-4,8-dihydroxy-3-phenoxy-7-bromoanthraquinone are obtained quite analogously, the colour shade of which, adsorbed on silica gel, is a blue of Indicator Number 14 (Colour Index Hue Indication Chart).
