실험 절차
To a solution of 310 mg (1.01 mmol) of 3,3,3-trifluoro-2-[1-(5-fluoro-2-methoxyphenyl)cyclopropylmethyl]propane-1,2-diol in 15 mL of MeOH was added 1.5 g (7.01 mmol) of sodium periodate. After 7 hours, the mixture was concentrated and the residue diluted with hexanes and filtered through diatomaceous earth. The crude residue was chromatographed on silica gel using hexanes to load the sample and then eluting with EtOAc-hexanes (0:100, then 0.25:99.75, then 0.5:99.5, then 1:99) to afford 200 mg of the title compound as a clear oil.
