摘要：
The involvement of Mannich bases derived from ortho-hydroxyacetophenones in amine-exchange reaction with pyrazole and methyl- and/or halogen-substituted pyrazoles was studied, The corresponding beta-(pyrazol-l-yl)ethyl ketones resulted in excellent yield and were characterized by elemental analysis, IR, H-1 and C-13 NMR spectroscopy.
