The process of Example 1 is repeated, replacing 64.3 parts of 5-nitro-1,4,4a,9a-tetrahydroanthraquinone by 71.3 parts of 5-nitro-2,3-dimethyl-1,4,4a,9a-tetrahydroanthraquinone (obtained from 1-nitronaphthoquinone and 2,3-dimethyl-1,4-butadiene by Diels-Alder reaction), to give 61.9 parts of 1-amino-6,7-dimethylanthraquinone in 99% purity, corresponding to a yield of 99% of theory.
