実験手順
A solution of 1,1′-thiocarbonyldi-2(1H)-pyridone (304 mg, 1.31 mmol) in anhydrous methylene chloride (13 mL) at 0° C. under a nitrogen atmosphere was treated with a solution of (S)-(−)-3-[3-fluoro-4-(tetrahydro-1,1-dioxido-2H-thiopyran-4-yl)phenyl]-5-aminomethyl-2-oxazolidinone, as prepared in Example 11, Step 1, (375 mg, 1.09 mmol) in anhydrous methylene chloride (88 mL) over 30 minutes. The resulting mixture was stirred at 0° C. for 30 minutes and at ambient temperature for 30 minutes and was then diluted with methylene chloride (40 mL), washed with water (25 mL) and brine (25 mL), dried over anhydrous sodium sulfate and concentrated in vacuo. The crude product was chromatographed on silica gel (230-400 mesh, 45 g), eluting with acetonitrile/methylene chloride (7.5/92.5), and those fractions with an Rf=0.64 by TLC (acetonitrile/methylene chloride, 20/80) were pooled and concentrated to give (S)-3-[3-fluoro-4-(tetrahydro-1,1-dioxido-2H-thiopyran-4-yl)phenyl]-5-isothiocyanatomethyl-2-oxazolidinone, mp 158-162° C. (dec.).
