실험 절차

19.1 g of sodium 1,1,1,3,3,3-hexamethyldisilazanate are added to a solution, cooled to -50° C., of 10 g of (4S,5S)-4-methyl-5-phenyl-3-[(2-methoxyphenyl)acetyl]oxazolidin-2-one in 150 cm3 of tetrahydrofuran, the mixture is stirred at this temperature for 45 minutes, and then 7.72 cm3 of methyl iodide are added. The reaction mixture is subsequently stirred at room temperature for 15 hours, then diluted with ethyl acetate, washed with 50 cm3 of water followed by 50 cm3 of saturated aqueous sodium chloride solution, dried over magnesium sulphate and concentrated to dryness under reduced pressure (2.7 kPa). The residue obtained is recrystallized from isopropyl ether, drained and dried. 4.2 g of (4S,5S)-4-methyl-5-phenyl-3-[(S)-2-(2-methoxyphenyl)propionyl]oxazolidin-2-one are obtained in the form of a white solid.
