실험 절차
Dess-Martin periodinane (849 mg) was added to a dichloromethane (20 ml) solution containing benzyl((2R)-1-hydroxy-3-phenylpropan-2-yl)carbamate (571 mg), followed by stirring at room temperature for 3 hours and 30 minutes. Insoluble matter was removed by filtration, and the solvent was distilled away under reduced pressure. The obtained residue was purified by silica gel chromatography (hexane:ethyl acetate=10:1 to 2:1), and a white solid of benzyl((2R)-1-oxo-3-phenylpropan-2-yl)carbamate (501 mg) was thus obtained.
