実験手順
A solution of (1R,2S)-[2-(3,4-difluoro-phenyl)-1-oxiranyl-ethyl]-carbamic acid tert-butyl ester (0.03 g, 0.1 mmol) in acetonitrile (1 mL) was treated with lithium triflate (0.032 g, 0.2 mmol) and stirred at ambient temperature for 20 minutes. Then 3-methoxybenzylamine (0.016 mL, 0.12 mmol) was added to the reaction neat in one portion. The reaction was stirred at ambient temperature for 14 hours. The reaction was poured into saturated ammonium chloride solution (5 mL), extracted with ethyl acetate, the organic phase separated, dried (MgSO4) and the solvent removed at reduced pressure. The product was obtained as an oil and used without further purification (0.041 g, 94%). MS: 437 (M+H, 100%).
