실험 절차

N-[[(5S)-3-[3-fluoro-4-(tetrahydro-1,1-dioxido-2H-1,2-thiazin-4-yl)phenyl]-2-oxo-5-oxazolidinyl]methyl]acetamide (200 mg, 0.52 mmol), powdered potassium carbonate (85 mg, 0.62 mmol) and methyl iodide (88 mg, 0.62 mmol) were stirred under nitrogen in dry DMF (1 mL) for 24 hours. After evaporation of the solvent, the residue is partitioned between chloroform (65 mL) and water (15 mL). The chloroform is dried (MgSO4), filtered and evaporated. The residue is chromatographed over silica gel, eluting with 2-6% methanol-chloroform. The product is obtained as a white foam (156 mg, 75%). HRMS (FAB) calc'd for M+H=400.1342; Found: 400.1343.
