Procedure
To a microwave vial with a stir bar was added (R)-4-((R)-1-tert-butoxyethyl)-3-(2-chloropyrimidin-4-yl)oxazolidin-2-one (43.6 mg, 0.145 mmol) and (S)-1-(3-((S)-tetrahydrofuran-3-yloxy)phenyl)ethanamine (25.1 mg, 0.121 mmol), followed by DMSO (605 uL) and DIEA (63.5 ul, 0.363 mmol). The vial was capped and the reaction mixture heated in a preheated oil bath at 110° C. for 21 hr. The mixture was diluted with water and extracted with EtOAc two times. The combined organic phases were washed with brine, dried over sodium sulfate, filtered, concentrated and dried on house vacuum to afford crude (R)-4-((R)-1-tert-butoxyethyl)-3-(2-((S)-1-(3-((S)-tetrahydrofuran-3-yloxy)phenyl)ethylamino)pyrimidin-4-yl)oxazolidin-2-one, as a brown solid film, (yield assumed quantitative). LCMS m/z 471.4 (M+H)+, Rt 0.85 min.
