Procedure

When 70.5 g of the 1-hydroxy-2-bromo-4-amino-7-chloroanthraquinone prepared above are subjected to a phenolate fusion as described in Example 467c, then 61 g, corresponding to 83% of theory, of 1-hydroxy-2-phenoxy-4-amino-7-chloro-anthraquinone are obtained, the colour shade of which on silica gel is a pink tinged with blue having the Indicator Number of 51 (Colour Index Hue Indication Chart).
