6.9 g (17.4 mmol) of 4-{4-[2-(4-pentyl-cyclohexyl)-vinyl]-phenyl}cyclohexane carboxylic acid methyl ester produced in Example 6-1 was dissolved in a mixture of toluene and ethanol (1:1 by volume %). 0.4 g of Pd/C was added to 200 mL of the resultant solution and reacted in hydrogenation reactor for 12 hours. After reaction, Pd/C was removed by filtration, concentrated under reduced pressure and recrystallized from chloroform and ethanol to obtain 6.1 g (88%) of 4-{4-[2-(4-pentyl-cyclohexyl)-ethyl]-phenyl}-cyclohexane carboxylic acid methyl ester.
