6.41 g (17.4 mmol) of 4-{4-[2-(4-propyl-cyclohexyl)-ethenyl]-phenyl}cyclohexane carboxylic acid methyl ester produced in Example 5-1 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 and concentrated under reduced pressure to obtain 5.2 g (80%) of 4-{4-[2-(4-propyl-cyclohexyl)-ethyl]-phenyl}-cyclohexane carboxylic acid methyl ester.
