실험 절차

Pyridine (2 mL) was dissolved in 15 mL of CH2Cl2. The solution was cooled to about 5° C. and stirred while while acetyl chloride (393 mg, 5 mmol) was added slowly. Next, a suspension of p-phenylphenol (0.85 g, 5 mmol) in 20 mL of CH2Cl2 was added dropwise over a 15 min period. The cooling bath was removed and stirring continued for 30 min. The solvents were removed under reduced pressure and 50 mL of ethyl acetate was added to dissolve the solids. The solution was extracted with water, dried over Na2SO4 and evaporated under reduced pressure.
