Reaction Steps

(3RS,4RS)-7-Hydroxy-3-(4-hydroxyphenyl)-3-methyl-4-[8-(4,4,5,5,5-pentafluoropentylthio)octyl]-2,3-dihydro-4H-benzopyran (53 mg, 0.095 mmol) was dissolved in 1,4-dioxane (1.2 ml), methanol (1.2 ml) and water (0.3 ml). NaIO4 (24 mg, 0.11 mmol) was added dropwise thereto, and the reaction mixture was stirred for 8 hours at room temperature and then filtered. The filtrate was concentrated and the residue was subjected to column chromatography (n-hexane:ethyl acetate=2:1) to obtain 38 mg (yield: 70%) of the title compound as a colorless oil.
