Procedure
A solution of 1,1,1-trifluoro-2-hydroxy-2-(4-trifluoromethoxyphenyl)-5-(3-phenoxyphenyl)pentane (0.18 g) in dichloromethane (6 cm3) was cooled to -78° C. and diethylaminosulphur trifluoride (0.1 g) was added. The mixture was allowed to warm to room temperature, stirred for a further 20 minutes and poured into water. The products were extracted into dichloromethane. The combined organic extracts were dried and the solvent evaporated under reduced pressure to leave an oil. The oil was purified by chromatography to give 1,1,1,2-tetrafluoro-2-(4-trifluoromethoxyphenyl)-5-(3-phenoxyphenyl)pentane.
