실험 절차
1,3,5-Triphenylpyrazoline (300 mg, 1.01 mmol), 150 mg of an oxidation catalyst and acetic acid (3.5 ml) were charged into a 100 ml three-neck flask, and were stirred at 120° C. for 2.5 hours under an oxygen atmosphere. The reaction mixture was filtered through Cerite. The filtrate was poured into a saturated aqueous solution of sodium hydrogencarbonate and then was extracted with ethyl acetate. The extract was condensed and 1,3,5-triphenylpyrazole was obtained as a pale yellow solid by means of silica gel column chromatography.
