Procedure

A dispersion of 268 g of 2,6-dimethoxyanthraquinone in 1800 ml of ethyleneglycol dimethylether was mixed with 75 g of sodium borohydride under stirring under a nitrogen atmosphere for one hour. The solution was then added dropwise to 6000 ml of a cold aqueous 1N hydrochloric acid, and the precipitates formed were filtered off, washed with water and dried to give 220 g of green 2,6-dimethoxyanthracene-9,10-diol.
