Reaction Steps
To a solution of methyl 8-[7-Methoxy-3-(4-methoxyphenyl)-3-methylthiochroman-4-yl]-2-octenate (160 mg, 0.34 mmol) in methanol (3 ml) and tetrahydrofuran (1 ml) were added sodium borohydride (129 mg, 3.40 mmol) and nickel (1 ml) chloride hexahydrate (16 mg, 0.068 mmol) at 0° C., which was then stirred at the same temperature for 2 hours. After the reaction was completed, water was added to the reaction mixture, and the resulting mixture was extracted with ethyl acetate. The extract was dried over anhydrous sodium sulfate, and concentrated under reduced pressure to give a crude product. This crude product thus obtained was subjected to silica gel column chromatography (n-hexane:ethyl acetate=4:1) to give the title compound (118 mg, yield: 73%; (3RS,4RS):(3RS,4SR)=4:1).
