실험 절차

To a round bottom flask with stir bar was added (R)-3-(2-(((S)-1-(2-(4-chlorophenyl)thiazol-5-yl)ethyl)amino)pyrimidin-4-yl)-4-((S)-1-hydroxyethyl)oxazolidin-2-one (19 mg, 0.04 mmol) followed by the addition of DCM (1 mL) under nitrogen. Mixture was cooled to 0° C. in a ice/water bath. To this cold solution was added DIEA (0.03 mL, 0.17 mmol) followed by the addition of methanesulfonyl chloride (10 μL, 0.13 mmol). Reaction mixture stirred for 1 hr at 0° C. The reaction mixture was then quenched with water and diluted with DCM. Phases partitioned and the aqueous phase extracted with DCM. Organic layers combined and washed with brine, dried (Na2SO4), filtered and concentrated to afford a orange residue of (S)-1-((R)-3-(2-(((S)-1-(2-(4-chlorophenyl)thiazol-5-yl)ethyl)amino)pyrimidin-4-yl)-2-oxooxazolidin-4-yl)ethyl methanesulfonate (21 mg, 0.04 mmol, 94% yield). LCMS m/z 524.2 (M+H)+, Rt 0.75 min.
