Nine substituted 2-(pyrazol-1-yl)-dialkylacetanilides were synthesized by N-alkylation of pyrazole and its derivatives with several 2-iodoacetanilides. The new compounds exhibited localanesthetic and antiarrhythmic actions. They have been characterized by elemental chemical analysis, UV-Vis, IR, 1H NMR, 13C NMR, SM spectra and pharmacology research.
