1,1-Ethylenedioxy-4-(3,4',5'-trifluorophenyl)-3-cyclohexen (100 g) was dissolved in ethanol (1 l), followed by adding Pd/C (5%) (40 g), stirring the mixture in a hydrogen gas atmosphere to carry out a catalytic reduction, filtering off the catalyst after the reaction, and distilling off the organic layer under reduced pressure, to obtain 1,1-ethylenedioxy4-(3',4',5'-trifluorophenyl)-cyclohexane (95 g).
