실험 절차

0.93 g of 3,5-di-t-butyl-4-hydroxybenzophenone oxime was dissolved in pyridine, and 0.28 g of acetyl chloride was added dropwise at room temperature. Thereafter, the mixture was stirred for 20 minutes. The reaction mixture was poured into ice water, extracted with benzene, washed with 4% HCl, water and a saturated aqueous solution of sodium bicarbonate, and dried. The solvent was distilled off, and the resulting crystals were recrystallized from ether/n-hexane to give 3,5-di-t-butyl-4-hydroxybenzophenone O-acetyloxime.
