SYNTHESIS OF NOVEL 4-(4-METHOXYBENZENE SULPHONYL)-3, 5-DIMETHYL/3-METHYL-5-PHENYL/3, 5- DIPHENYL/3, 5-DIMETHYL-1-PHENYL/3- METHYL -1, 5- DIPHENYL /1, 3, 5-TRIPHENYL PYRAZOLE

An efficient synthesis of novel 3, 4, 5-trisubstituted pyrazole (2a-c) and 1, 3, 4, 5-tetrasubstituted pyrazole (2d-f) by the reaction of (1a-c) with NH2-NH2/phenyl hydrazine in absolute C2H5OH.The structure of the various pyrazole derivatives (2a-f) has been elucidated from elemental analysis and spectral studies viz. IR, NMR.
