실험 절차

To a solution of bromobenzene (4.93 g, 31.4 mmol) in THF 125 mL under nitrogen at −78° was added t-BuLi (1.7 M in pentane, 50 mL). The mixture was stirred for 0.5 h at room temperature. The mixture was cooled down to −78° C. and a solution of (R)-1-((S)-1-phenylethyl)aziridine-2-carbaldehyde EBE 06048 (2.5 g, 14.3 mmol) in THF (16.7 mL) at −78° C. was added dropwise. The reaction mixture was treated with H2O (20 mL), the organic layer was separated and the aqueous phase was extracted with EtOAc. The combined organic layers were dried over MgSO4, filtered and concentrated in vacuo to give a residue that was purified by column chromatography using a gradient of 0-20% [v/v] EtOAc in cyclohexane to give (R)-phenyl((R)-1-((S)-1-phenylethyl)aziridin-2-yl)methanol EBE 06066 (3.13 g, 86% yield).
