Procedure

To a microwave vial with a stir bar was added (R)-4-((R)-1-(tert-butoxy)ethyl)-3-(2,6-dichloropyrimidin-4-yl)oxazolidin-2-one (75.0 mg, 0.224 mmol) and (S)-1-(4-(trifluoromethoxy)phenyl)ethanamine (59.7 mg, 0.247 mmol), followed by DMSO (0.9 mL) and DIEA (118 ul, 0.673 mmol). The vial was capped and the reaction mixture heated in a preheated oil bath at 85° C. for 2 hr. The mixture was diluted with brine and extracted with EtOAc two times. The combined organic phases were dried over sodium sulfate, filtered, concentrated and dried on house vacuum to afford crude (R)-4-((R)-1-(tert-butoxy)ethyl)-3-(6-chloro-2-(((S)-1-(4-(trifluoromethoxy)phenyl)ethyl)amino)pyrimidin-4-yl)oxazolidin-2-one as a brown solid film, (yield assumed quantitative). LCMS m/z 503.2 (M+H)+, Rt 1.24 min.
