Synthesis and Reactivity of Some Mannich Bases. VI. New Arylamine Mannich Bases Derived From 2-Hydroxy-5-Methylacetophenone

The amine exchange reaction has been applied for obtaining a new series of arylamine Mannich bases from variously substituted aromatic amines and 3-(dimethylamino)-1-(2'-hydroxy-5'-methylphenyl) propan-1-one. The structures of the newly synthesised Mannich bases have been investigated by IR, 1H- and 13C-NMR and shown to be in good agreement with the proposed ones.
