A solution of 1 g of β-[trans-4-[trans-4-(2-(1,3-dioxolan-2-yl)ethyl)cyclohexyl]cyclohexyl ]-4-fluorostyrene in 10 ml of toluene and 5 ml of ethanol is hydrogenated with 500 mg of 5 percent palladium-charcoal at room temperature and normal pressure until the hydrogen uptake comes to a standstill. The black suspension is subsequently filtered. Evaporation of the filtrate gives 1-[2-[trans-4-[trans-4-(2-(1,3-dioxolan-2-yl)ethyl)cyclohexyl]cyclohexyl]ethyl]-4 -fluorobenzene.
