실험 절차

12.0 g (39.3 mmol) of 1-(4-hexylphenyl)ethanone was dissolved in 23.6 g (393 mmol) of glacial acetic acid mixed with 4.95 g (275 mmol) of water and 5.79 g (58.9 mmol) of sulfuric acid and heated at 150° C. for 6.5 hours under reflux. After completion of the reaction, the reaction solution was diluted with 400 mL of water and extracted with ethyl acetate. The resulting organic layer was dried over anhydrous magnesium sulfate and filtered, and the filtrate was concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography using ethyl acetate:hexane (1:20 to 1:4) as the eluent to give 5.74 g of the desired product as white crystals.
