Abstract
249,717. Carpmael, W., (Farbenfabriken vorm. F. Bayer & Co.). June 29, 1925. #-Aminoalkylaminonaphthalenes and their unsulphonated substitution products are obtained by beating a naphthol-o-carboxylic acid with an aliphatic diamine in presence of a sulphite. Examples are given of the preparation of w-aminoethyl-1-aminonaphthalene, #-aminoethyl-2-aminonaphthalene, #-aminobutyl-2-aminonaphthalene, and #-aminoethylaminoethyl-2-aminonaphthalene.
