Özet

The reactions of 4-benzoyl-1-(2,4-dinitrophenyl)-5-phenyl-1H-pyrazole-3-carboxylic acid (2b), 4-benzoyl-1-(4-nitropheny1)-5-phenyl-1H-pyrazole-3-carboxylic acid chloride (3a) and 4-benzoyl-1-(2,4-dinitrophenyl)-5-phenyl-1H-pyrazole-3-carboxylic acid chloride (3b) can easily be converted into the corresponding ester 5, from reaction with various alcohols. It has been demonstrated that with the ! variation in reaction conditions, the reaction changes leading to different products. All newly synthesized compounds were characterized I by elemental analysis, IR, H-1 and C-13 NMR spectral data. All compounds were compared with their previous analogues.
