실험 절차

To a round bottom flask containing (S)-4-((R)-1-azidoethyl)-3-(2-(((S)-1-(2-(4-chlorophenyl)thiazol-5-yl)ethyl)amino)pyrimidin-4-yl)oxazolidin-2-one (14 mg, 0.03 mmol) and stir bar was added THF (1 mL) and trimethylphosphine (0.06 mL, 0.06 mmol, 1.0 M in THF). The resulting reaction mixture allowed to stir 2 hr at RT. A second addition of trimethylphosphine (0.06 mL, 0.06 mmol) occurred and the mixture allowed to stir 1.5 hr at RT. Reaction was quenched by the addition of a saturated solution of NH4Cl and EtOAc. The phases were partitioned and aqueous phase extracted with EtOAc. Organic phases combined and washed with brine, dried (Na2SO4), filtered and concentrated to a yellow residue. Residue dissolved in DMSO and purified by reverse phase HPLC. Product fractions combined, frozen and lyopholyzed to afford (S)-4-((R)-1-aminoethyl)-3-(2-(((S)-1-(2-(4-chlorophenyl)thiazol-5-yl)ethyl)amino)pyrimidin-4-yl)oxazolidin-2-one (2.6 mg, 4.60 μmol, 15% yield) as a TFA salt.
