Preparation of n-aryl-substituted 2-aminoalkyl-2-hydroxyalkylamines and n-aryl-substituted piperazines |
| abstract |
N-Aryl-substituted 2-amino-alkyl-2-hydroxyalkylamines and N-aryl-substituted piperazines Ia and Ib respectively <IMAGE> (Ar=aryl; R1=hydrogen, methyl, identical or different, R2=hydrogen, alkyl) are prepared by reacting an N,N-di(2-hydroxyalkyl)-N-arylamine II <IMAGE> II with ammonia or a primary amine III H2N-R2 III at elevated temperature and under elevated pressure in the presence of hydrogen and of a catalyst which is a supported catalyst whose active mass predominantly contains copper and/or nickel and/or cobalt in the form of the metal or an oxide. |
