Steps:

8. Synthesis of compound 1, Linezolid

Compound 9 (100 mg, 0.34 mmol) was dissolved into 5 mL of anhydrous dicholoromethane in a 25 mL round bottom flask. The mixture was treated with Ac₂O (0.2 mL, 1.59 mmol) and TEA (0.28 mL, 2.0 mmol) at room temperature. After 3 hours, dilute the mixture with EtOAc (40 mL).Wash the mixture with HCl (0.1 M, 5 mL), Sat. NaHCO₃ (10) and brine (10 mL).Dry the organic layer with Na₂SO₄. Filter the organic layer and concentrate the organic layer at reduced pressure, the desired product was purified by silica gel column. Yield, 129 mg, 98%. ¹H NMR (400 MHz, DMSO-d6) δ 8.27 (s, 1H), 7.49 (d, J = 15.0 Hz, 1H), 7.18 (d, J = 8.6 Hz, 1H), 7.04 (t, J = 9.2 Hz, 1H), 4.72 (s, 1H), 4.08 (t, J = 8.8 Hz, 1H), 3.71 (m, 4H), 2.95 (m, 4H), 1.85 (s, 3H). ¹³C NMR (101 MHz, DMSO-d6) δ 170.51, 156.26, 154.51, 153.83, 135.96 (d, J = 8.8 Hz), 133.89 (d, J = 10.6 Hz), 119.60 (d, J = 4.0 Hz), 114.42 (d, J = 2.6 Hz), 107.16, 106.90, 72.03, 66.61, 51.14, 47.73, 41.88, 22.87. ¹⁹F NMR (376 MHz, DMSO) δ -121.26.
