4-benzoyl-1-(-4-methoxyphenyl)-5-phenyl-1H-pyrazole-3-carboxylic acid 2, obtained from 4-benzoyl-5-phenyl-2,3-furandione 1 and 4-methoxy benzaldehyde-phenyl hydrazone, was converted via reactions of its acid chloride 3 with various N-nucleophiles to the corresponding urea 8a−e or amide 6, and 7a−b derivatives, respectively. The amide 6 compound was converted to nitrite 9. Decarboxylation product 4, ester 5a−b, and cyclization products 10−12 with various hydrazines were obtained from the acid. The antimicrobial activities of the synthesized pyrazole carboxylic acid derivatives on Bacillus cereus, Escherichia coli, Micrococcus luteus, Staphylococcus aureus, and Saccharomyces cerevisiae were evaluated.
