Procedure

10% Pd/C (1.04 g) was added to a solution of the ethyl 10-[(3R,4R)-7-methoxy-3-(4-methoxyphenyl)-3-methylthiochroman-4-yl]-2-(4,4,5,5,5-pentafluoropentyl)-8-decenoate (3.46 g, 5.268 mmol) in tetrahydrofuran (60 ml) followed by stirring for 23 hours at room temperature under a hydrogen stream. After the reaction mixture was filtered, the solvent was distilled off and the resulting residue was purified by silica gel column chromatography (eluent: ethyl acetate/hexane=1/10) to give ethyl 10-[(3R,4R)-7-methoxy-3-(4-methoxyphenyl)-3-methylthiochroman-4-yl]-2-(4,4,5,5,5-pentafluoropentyl)decanoate (3.23 g, Yield 93%) as an oil.
