A solution of (triethoxymethyl)benzene (360 mg, 1.6 mmol, 5.0 equiv. in 5 mL of benzene and 0.5 mL of glacial AcOH) was added to (S)-2-((4-((S)-4-isopropyl-2-oxooxazolidin-3-yl)pyrimidin-2-yl)amino)propanehydrazide (99 mg, 0.30 mmol, 1.0 equiv.), the reaction mixture was stirred at reflux for 1.5 hours, the solvent was removed to yield the crude product. Silica gel column chromatography (ethyl acetate in heptane 10 to 90%) to yield (S)-4-isopropyl-3-(2-(((S)-1-(5-phenyl-1,3,4-oxadiazol-2-yl)ethyl)amino)pyrimidin-4-yl)oxazolidin-2-one (21.2 mg, white solid) in 15.9% yield. HRMS(B) m/z 395.1820, (M+H)+, RT=2.42 min
