Triphenylphosphine (2.82 g, 10.8 mmol) was added portionwise to a solution of 5-(S)-azidomethyl-3-[4′-triphenylmethylthio-3′-fluorophenyl]oxazolidine-2-one (5.00 g, 9.79 mmol) in THF (40 mL), and the mixture stirred for 2 h at r.t. Water (1.41 mL, 78.3 mmol) was added, and the mixture heated at 40° C. overnight. Solvent was removed under vacuum, and the oily residue purified by column chromatography (eluent: DCM, then 10% MeOH in DCM). Yield 3.56 g (75%). MS (m/z): [M+H]+=485.
