In a 2-liter three-necked flask equipped with a stirring device and a nitrogen substituting device, 169.6 g of 1,3-diphenyl-2-n-hexyl-2-propen-1-ol, 0.4 milliliters of trifluoroacetic acid and 17 g of a Pd-C catalyst (a 5% product, containing 55.9% of water) were introduced, and stirred at 50° C. and contacted with hydrogen gas. After stirring for 30 hours, the catalyst was filtered off, water was added, and an extraction was carried out with n-heptane. After washing with sodium hydrogencarbonate and water, the solution was dried with anhydrous sodium sulfate. After removing off the solvent by a rotary evaporator and dissolving the residue in a small amount of n-heptane, a separating operation was carried out by a column chromatography with silica gel. By removing off the solvent again and carrying out a distillation under a decreased pressure, to obtain 98.9 g of 1,3-diphenyl-2-n-hexyl propane as colorless liquid.
