Process for the dehydration of substituted 4-dimethylamino-2-aryl-butan-2-ol compounds and process for the preparation of substituted dimethyl-(3-aryl-butyl)- amine compounds by heterogeneous catalysis
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.
