Reaction Steps

To a microwave vial containing (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) in DMF (1 mL) was added sodium azide (13 mg, 0.20 mmol). Resulting reaction mixture heated to 50° C. for 1 hr in a sand bath then to 80° C. for 42 hr. Reaction mixture was diluted with water and extracted with EtOAc. Organic phases combined, washed with brine, dried (Na2SO4), filtered and concentrated to a yellow residue of (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, 0.030 mmol, 74.2% yield). LCMS m/z 471.2 (M+H)+, Rt 0.92 min.
