Mode opératoire

0.27 g of Pd/C was added to 6.53 g of the compound 1-1-3-18 having been dissolved in 50 mL of toluene and 50 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 1.8 g of 1-(2,3-difluoro-4-ethoxy-6-methylphenyl)-2-(4-pentylcyclohexyl)ethane (Compound 1-1-3-5) as colorless crystals.
