Abstract
292,615. I. G. Farbenindustrie Akt.- Ges. June 23, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Aliphatic diamines, containing one secondary and one primary, secondary or tertiary amino group, are prepared by treating a secondary aromatic amine or nuclear-substitution derivative thereof with an aminoalkyl halide, and splitting off the aryl residue from the product. The amino substituent of .the secondary aromatic amine may be an alkyl, hydroxyalkyl or aminoalkyl group. The aminoalkyl halide may contain a tertiary aliphatic amino group, or a primary or secondary aliphatic amino group substituted by an aryl or arylidene group which is subsequently removed. The splitting off of the aryl residue may be effected by producing a p-nitroso compound or other compound containing a negative substituent, and decomposing the product to liberate the amine by means, for example, of alkali. The products are useful as drugs or as intermediates for the manufacture of drugs and dyestuffs. According to the examples (1) N-methyldiethylaminoethylaniline, obtained from monomethylaniline and diethylaminoethyl chloride, is treated in cold hydrochloric acid solution with sodium nitrite, and to the resulting nitroso compound sodium bisulphite solution is slowly run in; after standing some hours, caustic soda is added and the alpha-diethylamino-#-methylaminoethane distilled in steam; in an analogous manner as-triethylethylenediamine is obtained from N-ethyldiethylaminoethylaniline; (2) monomethylaniline is treated with alpha-dimethylamino-gamma-methylpropyl chloride and from the product, alpha-dimethylaminogamma-methylaminobutane is split off by the process of the preceding example; in the same way alpha-dimethylamino-#-methyl-gamma-methylaminobutane is split off from the product of reaction of monoethylaniline and alpha-dimetbylamino-#gamma-dimethylpropyl chloride, and a-diethylamino-#-diethylaminoethylaminoethane from the product of reaction of N-diethylaminoethylaniline and diethylaminoethyl chloride
