6.83 g of aluminum chloride was added to 20.0 g of benzene, followed by cooling/stirring at 3° C., and 40.4 g of cyclohexyl chloride was slowly added dropwise. After the dropwise addition, the mixture was stirred at room temperature for 5 hours and poured into ice water. The organic layer was extracted with ethyl acetate, and the obtained organic layer was distilled off under reduced pressure at 40° C. After further distillation off under reduced pressure at 170° C., the product was cooled to room temperature, charged into 50 ml of acetone and thereby recrystallized. The crystal precipitated was collected by filtration to obtain 14 g of tricyclohexylbenzene.
