Procedure

Sodium periodate (0.014 g, 0.065 mmol) in water (0.5 mL) was added to 5-(S)-acetamidomethyl-3-[4′-(2″-hydroxyethyl)thio-3′-fluorophenyl]-oxazo-lidine-2-one (0.020 g, 0.061 mmol) in methanol (1 mL), and the mixture was stirred at r.t overnight. Solvent was removed under vacuum, and the residue dissolved in ethyl acetate (ca. 5 mL). Resulting solution was washed with water, brine, and dried (MgSO4). Solvent was removed under vacuum, and the crude product purified by TLC (eluent: 10% methanol in dichloromethane). Yield 0.018 g (86%). MS (m/z): 345 [M+H]+. 1H NMR.
