実験手順
To a stirred solution of (R)-4-phenyl-2-oxazolidinone (174 mg, 1.06 mmol) in THF (4 mL) at 0° C., add NaH (4.3 mg, 60% emulsion in oil, 0.106 mmol). Allow the temperature to rise to room temperature over 30 min., then add tetra n-butylammonium bromide (34 mg, 0.106 mmol) to the mixture and stir for another 30 min. to obtain (R)-4-phenyl-2-oxazolidinone tetra n-butylammonium salt.
