To a round bottom flask containing a stir bar and (R)-4-((S)-1-(tert-butoxy)ethyl)-3-(2-(((S)-1-(2-(4-chlorophenyl)thiazol-5-yl)ethyl)amino)pyrimidin-4-yl)oxazolidin-2-one (82 mg, 0.16 mmol) was added DCM (1 mL) followed by the addition of TFA (1 mL). Resulting reaction mixture allowed to stir 30 min at RT. The volatiles were then removed and the residue neutralized by the addition of a saturated solution of NaHCO3. The aqueous mixture was then extracted with DCM. Organic phases combined, washed with water, brine, dried (Na2SO4), filtered and concentrated to a brown foam of (R)-3-(2-(((S)-1-(2-(4-chlorophenyl)thiazol-5-yl)ethyl)amino)pyrimidin-4-yl)-4-((S)-1-hydroxyethyl)oxazolidin-2-one (61 mg, 0.14 mmol, 84% yield) which was used without further purification. LCMS m/z 446.2 (M+H)+, Rt 0.71 min.
