Abstract

FIELD: organic chemistry. SUBSTANCE: product: 1-(4-formylphenyl)-3,5-diphenylpyrazole of the formula (I):. Method of synthesis of 1-(4-formylphenyl)-3,5-diphenylpyrazole involves oxidation of 1-(4-formylphenyl)-3,5-diphenylpyrazoline with sodium bichromate at boiling in acetic acid at mole ratio of the parent reagents pyrazoline : sodium bichromate = 1:0.5 followed by reaction mixture exposition for 20-40 min. EFFECT: improved method of synthesis.
