Vorschrift

0.1 g of Pd/C was added to the compound 1-1-3-17 having been dissolved in 20 mL of toluene and 20 mL of Solmix, and under a hydrogen atmosphere, the mixture was stirred at room temperature until hydrogen was not absorbed. Pd/C was removed, and the solvent was distilled off. The residue was purified by silica gel column chromatography and recrystallization to obtain 2.01 g of 1-(2,3-difluoro-4-ethoxy-6-methylphenyl)-2-(4-propylcyclohexyl)ethane (Compound 1-2-3-4) as colorless crystals.
