실험 절차

Into a reactor were introduced 2.80 g (11.3 mmol) of the 1,1-bis(4-fluorophenyl)propanol, 60 mL of toluene, and 14 mg of p-toluenesulfonic acid monohydrate under a nitrogen atmosphere. Azeotropic dehydration was conducted for 1 hour with toluene refluxing. After being cooled, the reaction mixture was washed with saturated aqueous sodium hydrogen carbonate solution and saturated aqueous sodium chloride solution, subsequently dried with anhydrous magnesium sulfate, and then concentrated under reduced pressure to obtain 2.39 g (92%) of the target compound as white crystals.
