实验步骤: 2.40 g (14.7 mmol) of separately prepared 2-methyl-1-p-tolylpropan-2-amine was dissolved in 20 mL of methylene chloride, and 2.60 g (10.0 mmol) of separately prepared t-butyl 3-(trichloromethyl)-1,2-oxaziridine-2-carboxylate in 10 mL of methylene chloride was added under cooling with ice. The reaction slution was stirred under cooling with ice for 30 minutes and at room temperature for 1 hour, and the methylene chloride was removed under reduced pressure. The resulting residue was purified by silica gel column chromatography using hexane-ethyl acetate (100:0 to 0:100) as the eluent to give 1.61 g of the desired product as colorless crystals. under cooling with ice the methylene chloride was removed under reduced pressure The resulting residue was purified by silica gel column chromatography
