Procedure

To a suspension of (R)-4-((R)-1-(tert-butoxy)ethyl)-3-(2-fluoropyrimidin-4-yl)oxazolidin-2-one (30.0 mg, 0.106 mmol) and (S)-1-(4-(trifluoromethoxy)phenyl)ethanamine (38.4 mg, 0.159 mmol) in DMSO (0.53 mL), was added DIEA (64.7 ul, 0.371 mmol) in a microwave vial. The vial was capped and the reaction mixture heated in a preheated oil bath at 100° C. for 3 hr. The mixture was diluted with dilute brine and extracted with EtOAc two times. The combined organic phases were washed with brine, dried over magnesium sulfate, filtered, concentrated and dried on house vacuum to afford crude (R)-4-((R)-1-(tert-butoxy)ethyl)-3-(2-(((S)-1-(4-(trifluoromethoxy)phenyl)ethyl)amino)pyrimidin-4-yl)oxazolidin-2-one as a clear colorless oil which was used without further purification (yield assumed quantitative). LCMS m/z 469.3 (M+H)+, Rt 0.98 min.
