In 20 ml of methylene chloride were dissolved 211 mg (0.48 mmol) of 4-chlorobenzyl trans-4-[(1E,3E)-4-[4-(trifluoromethyl)phenyl]-1,3-butadienyl]cyclohexyl sulfide, and 104 mg (0.48 mmol) of m-chloroperbenzoic acid (purity: 80%) were added to the solution at 0° C. followed by stirring of the resulting mixture for 5 minutes. An aqueous sodium sulfite solution and ethyl acetate were added to the reaction mixture and the organic layer was washed with an aqueous sodium hydrogencarbonate solution and an aqueous NaCl solution. After the mixture was dried, the crude product obtained by evaporation of the solvent was recrystallized from a mixed solvent of ethyl acetate-hexane to obtain 168 mg (yield: 77%) of the title compound having a melting point of 212 to 214° C.
