Abstract
4-[5-(4-methylphenyl)-3-(trifluoromethyl)-1H-pyrazol-1-yl]-benzene sulfonamide was synthesized from para-methyl-acetophenone and ethyl trifluoroacetate.The structure of the synthesized product was characterized by means of FT-IR and 1HNMR. The effects of the amount of base, solventt, the reaction temperature and time on the yield of the product were investigated.
