Procedure
Formic acid (11.3 g) and toluene (5 ml) were added to 1,1-ethylenedioxy-4-(3',5'-difluoro-4'-trifluoromethylphenyl)cyclohexane (15.7 g), followed by heating the mixture under reflux with stirring for 2 hours, adding the reaction solution to water (50 ml), extracting with ethyl acetate (100 ml), drying the organic layer over anhydrous MgSO4, and distilling off the solvent under reduced pressure, to obtain 4-(3',5'-difluoro-4'-trifluoromethylphenyl)cyclohexanone (12.0 g).
