실험 절차

Add 2(R)-trifluoromethanesulfonyloxypropionic acid methyl ester (6 g, 25.42 mmol) to a solution of (2R,3S,4S)-2-amino-3-benzyloxy-4-dibenzylamino-5-(3,5-difluorophenyl)-pentan-1-ol bishydrochloride (4.7 g, 7.94 mmol) and triethylamine (5 mL, 35.87 mmol) in dichloromethane (150 mL). Stir the reaction mixture at room temperature for 68-hours. Dilute with dichloromethane and wash with 5% aqueous citric acid, saturated aqueous sodium chloride, dry (magnesium sulfate), filter, concentrate and purify (silica gel chromatography, eluting with 10:90 to 20:80 ethyl acetate:hexanes) to give the desired compound (2.93 g, 65%).
