Большой спасиб конечно, но рассчитывал получить пару слов о японском патенте...

Abstract
1-Amino-4-hydroxyanthraquinone derivs., as starting materials for disperse dyes and anthraquinone dyes, are prepd. by treating an anthraquinone compd. (I; R = alkyl Ph, hydroxyalkyl, alkoxyalkyl, or phenoxyalkyl group) with ammonia water. Thus, 27 parts 1,4-dihydroxy-2-methoxyanthraquinone and 190 parts of a 20% ammonia water were heated 7 hr at 100 and under pressure, filtered, and dried to give 27.2 parts 1-amino-4-hydroxy-2-methoxyanthraquinone [2379-90-0]. 1-Amino-4-hydroxy-2-(-hydroxyethoxy)anthraquinone [17869-07-7] was also similarly prepd. from I (R = CH2CH2OH).
