A solution of (R)-4-((R)-1-(tert-butoxy)ethyl)-3-(2-fluoropyrimidin-4-yl)oxazolidin-2-one (112 mg, 0.40 mmol), (S)-1-phenylethanamine (58 mg, 0.48 mmol, 1.2 equiv), and DIPEA (153 mg, 1.2 mmol, 3.0 equiv) in DMSO (4.0 mL) was heated at 100° C. for 90 min. The reaction mixture was poured into 5 ml of water, extracted with EA (2×10 ml), the solvent was removed to yield the crude product. Silica gel column chromatography (ethyl acetate in heptane 10 to 50%) provided the pure product (142 mg, white solid) in a 93% yield. HRMS m/z 385.2231 (M+H)+, RT=3.35 min.
