실험 절차

To a solution of 7-methoxymethoxy-3-(4-methoxymethoxyphenyl)-3-methyl-4-(4-(3-(2-(4,4,5,5,5-pentafluoropentylthio)ethoxy)-(R)-2-hydroxypropyloxy)phenyl)chroman (440 mg, 0.613 mmol) in methanol (9 ml) was added 6N HCl (3 ml) at room temperature, which was stirred for 40 minutes at 70° C. Water was added thereto, and the resulting solution was extracted with ethyl acetate. Then, the organic layer was washed with water and saturated sodium chloride solution, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was subjected to flash chromatography on silica gel (n-hexane:ethyl acetate=3:2) to give the title compound (269 mg, yield 68%) as a white solid.
