Synthesis of novel derivatives of some of pyrazole 3-carboxylic acids and 3-carboxylate

In this study, as initial materials 4-benzoyl-1-(3-nitrophenyl)-5-phenyl-1H-pyrazole-3-carbonyl chloride (1), ethyl 3-(chlorocarbonyl)-1-(3-nitrophenyl)-5-phenyl-1H-pyrazole-4-carboxylate (2) ve 2-(3-aminophenyl)-3,4-diphenyl-2H-pyrazolo[3,4-d]pyridazin-7(6H)-one (3) synthesis of new derivatives and is intended to make in charactacions.Firstly of obtained pyrazole -3-carboxylic acids carboxyl groups with SOCl2 in active was converted açil klorürlerine (1 ve 2) these compounds is a new series put on various with nukleofils reaction karboksilat derivatives and synthesis of bis karboksamit been built.On the other hand, is performed before the synthesis of compounds with 3 primary aromatic amine group, put on 0 0C'de by reaction with NaNO2 and HCl was converted to salt diazonyum. Diazonyum of compounds, the active hydrogen containing various ß-diketonlar, phenols and ß-napthol with clenching new compounds were obtained as a result.Structures of resultant compounds examined with IR, 1H-NMR, and 13C-NMR, spectroscopy methods.
