Synthesis and Biological Activity of Compounds Obtained by Reacting Methyl Aroylpyruvates with Sulfadimidine

Resumo

The reaction of methyl aroylpyruvates and 2-(4-aminobenzenesulfamido)-4,6-dimethylpyrimidine in glacial acetic acid in the presence of anhydrous sodium acetate afforded (2Z)-4-aryl-2-hydroxy-N-{4-[(4,6-dimethylpyrimidin-2-yl)sulfamoyl]phenyl}-4-oxobut-2-enamides. Reaction of the above reagents in a mixture of acetic acid and ethanol (1: 1) in the absence of anhydrous sodium acetate gave methyl (2Z)-4-aryl-2-{4-[(4,6-dimethylpyrimidin-2-yl)sulfamoyl]phenylamino}-4-oxobut-2-enoates. Analgesic and anti-inflammatory activities of the synthesized compounds was studied.
