실험 절차
A mixture of 4-benzoylbenzoic acid (20 g, 88.4 mmole), toluene (5 mL), p-toluenesulfonic acid (1 g) and ethanol (20 mL) was refluxed for 12 hours, cooled, washed with 5% sodium carbonate, and neutralized by water wash. The organic layer was dried over anhydrous magnesium sulfate and concentrated to obtain 22 g ethyl 4-benzoylbenzoate in a yield 90.5%.
