Abstract

337,047. Carpmael, A., (I. G. F'arbenindustrie Akt.-Ges.). July 26, 1929. Aminohydroxyanthraquinones and substitution products thereof are obtained by condensing an acyl- or aroyl-aminophenol, homologue or substitution product thereof with phthalic anhydride, or a substitution product thereof, in presence of an agent such as aluminium chloride, saponifying and ring-closing when necessary in the customary manner. According to examples, (1) 2: 3- aminohydroxyanthraquinone is obtained by condensing 2 : 2<1> - dimethoxydiphenyl urea and phthalic anhydride in presence of aluminium and sodium chlorides, followed by ring-closure of the benzoyl benzoic acid formed intermediately and saponification; the corresponding 1: 2-compound is also formed; (2) 1-amino-4-hydroxyanthraquinone is obtained in a similar manner from 1- benzoylamino-4-phenol with the intermediate formation of a benzoyl benzoic acid derivative; (3) o-dimethoxydiphenyl urea is condensed with 3-chlorophthalic anhydride to give a 3'-amino-4'- hydroxy (or methoxy)-6-chlorobenzoyl-2-benzoic acid, and, then the 2-amino-3-hydroxy-5-chloroanthraquinone; (4) 1-amino-3-chloro-6-methoxybenzene and phthalic anhydride give the 1- hydroxy-2-amino-4-chloroanthraquinone; (5) the the urea from 1-amino-3-methyl-6-methoxybenzene and phthalic anhydride is similarly condensed to give the 1 - hydroxy - 4 - methyl-2-aminoanthraquinone.
