실험 절차

20.7 g of the crude 1-hydroxy-1-(2-trifluoromethyl-3-fluoro-4-ethoxy-5-trimethylsilylphenyl)-2-(4-(4-propylcyclohexyl)cyclohexyl)ethane obtained in the first step was dissolved in toluene. 0.68 g (3.57 mmol) of p-toluene sulfonic acid monohydrate was added and refluxed under heating for 2 hours while dewatering by using a Dean Stark apparatus. The reaction mixture was poured into 200 ml of an aqueous sodium hydrogen chloride solution and extracted with 200 ml of toluene. The organic layer was washed with 200 ml of water and then with 100 ml of an aqueous saturated sodium chloride solution successively and, after drying over anhydrous magnesium sulfate, it was concentrated under a reduced pressure to obtain 16.03 g of a crude β-(4-(4-propylcyclohexyl)cyclohexyl)-2-trifluoromethyl-3-fluoro-4-ethoxy-5-trimethylsilyl styrene.
