METHOD FOR DEHYDRATING SUBSTITUTED 4-DIMETHYLAMINO-2-ARYL-BUTAN-2-OL COMPOUNDS AND METHOD FOR PRODUCING SUBSTITUTED DIMETHYL-(3-ARYL-BUTYL)-AMINE COMPOUNDS BY MEANS OF HETEROGENEOUS CATALYSIS

摘要

Process for the preparation of substituted dimethyl-(3-aryl-butyl)-amine compounds. The process comprises dehydration by heterogeneous catalysis of substituted 4-dimethylamino-2-aryl-butan-2-ol compounds, to form substituted dimethyl-(3-aryl-but-3-enyl)-amine intermediates, which are then converted by hydrogenation with hydrogen to substituted dimethyl-(3-aryl-butyl)-amine compounds.
