実験手順

(5R)-3-[4-(3,6-dihydro-2H-thiopyran-4-yl)-3-fluorophenyl]-5-(1,2,3-triazol-1-ylmethyl)oxazolidin-2-one (Example 83; 1.25 g, 3.5 mmol) was stirred in a mixture of methanol and ethyl acetate (1:1, 50 ml) at ambient temperature. Sodium periodate (0.93 g, 4.3 mmol) in water (10 ml) was added dropwise, and it was stirred for 18 hours. Precipitated salts were removed by filtration and solvents were removed under vacuum. The residue was chromatographed on silica gel, washing with 25% acetone in dichloromethane, then eluting with 5 to 7% methanol in dichloromethane to give the title product (1.152 g).
