Procedure

1-(4-Fluoro-3-phenoxyphenyl)-4-(4-methoxyphenyl)-4-trifluoromethyl-2-pentene (15.12 g; 37.76 mmol) was hydrogenated in methanol (200 ml) with hydrogen using Raney nickel (5 g) at room temperature and under atmospheric pressure. After the calculated amount of hydrogen had been taken up, the catalyst was filtered off and the solvent removed under reduced pressure. After chromatography on silica gel using ethyl acetate/hexane as eluant, there was obtained a 10.1 g of product (=61.8% of theory).
