A solution of 2,5-difluorobromobenzene (1.33 mmol) in THF (10 ml) is added dropwise to magnesium (1.44 mmol). After the addition is completed, the reaction mixture is stirred at 50° C. for 2 hrs. To the reaction mixture, a solution of 4-(trans-4-propylcyclohexyl)cyclohexanone (1.03 mmol) in THF (10 ml) is added dropwise. After the addition is completed, the reaction mixture is stirred for 2 hrs at 50° C. A saturated aqueous solution of ammonium chloride (10 ml) is added in small portions and the aqueous layer is extracted with ethyl acetate (100 ml) twice. The extract is washed with water, and then dried over anhydrous magnesium sulfate. The titled compound is obtained by evaporation of the solvent under reduced pressure.
