Reaction Conditions

Reaction Steps

2 mol of anhydrous hydrofluoric acid is poured into an autoclave which has been cooled to 0° C. A mixture of 0.18 mol of carbon tetrachloride and 0.06 mol of 1-[trans-4-(trans-4-n-propylhexyl)cyclohexyl]-2-(4-hydroxy- 3,5-difluorophenyl)ethane (Example 1) is then added. The mixture is stirred at 150° for about 8 hors, cooled, poured into ice water, and the autoclave is subsequently washed out with ether. The two phases are combined, stirred for about 30 minutes, separated, and the ether solution is washed with 5% KOH solution until it remains alkaline. The organic phase is dried, filtered, evaporated, and the residue is purified to give 1-[trans-4-(trans-4-n-propylcyclohexyl)cyclohexyl]-2-(4-trifluoromethoxy-3,5-difluorophenyl)ethane.
