実験手順

To solution of methyl 2,3-dibromopropionate (25 mL, 198 mmol) in toluene at 5° C. was added triethylamine (55 mL, 0.39 mmol) in toluene (100 mL). After stirring for 5 min (S)-(1)-phenethylamine (25 mL, 198 mmol) in toluene (100 mL) was added dropwise. The suspension was refluxed for 3 h and allowed to cool down, filtered and the volatiles were evaporated under reduced pressure to give a residue that was purified by column chromatography (950 g of silica gel) with a gradient of 0-20% EtOAc in cyclohexane to yield to (S)-methyl 145)-1-phenylethyl)aziridine-2-carboxylate EBE 06044A as a yellow oil (17.31 g, 43% yield) and (R)-methyl 1-((S)-1-phenylethyl)aziridine-2-carboxylate EBE 06044B as a yellow oil (15.14 g, 37% yield).
