To a round bottom flask containing (R)-4-((S)-1-(tert-butoxy)ethyl)-3-(2-fluoropyrimidin-4-yl)oxazolidin-2-one (502 mg, 1.77 mmol) was added DCM (4 mL) and TFA (4 mL). Resulting reaction mixture stirred for 1 hr at room temperature. The volatiles were then removed and the residue neutralized with a saturated solution of NaHCO3. The aqueous mixture was extracted with EtOAc. Organic phases combined, washed with water, brine, dried (Na2SO4), filtered and concentrated to a colorless residue of (R)-3-(2-fluoropyrimidin-4-yl)-4-((S)-1-hydroxyethyl)oxazolidin-2-one (382 mg, 1.68 mmol, 95% yield). LCMS m/z 228.1 (M+H)+, Rt 0.44 min.
