PROCEDURE
实验过程
Dissolve (R)-5-[(1S,2S)-2-amino-3-(3,5-difluorophenyl)-1-hydroxypropyl]-2,2-diphenylmorpholine-4-carboxylic acid tert-butyl ester (0.163 g, 0.31 mmol) in tetrahydrofuran (4 mL). Add triethylamine (0.044 g, 0.44 mmol) and acetic anhydride (0.036 g, 0.35 mmol). Stir 90 minutes and dilute with ethyl acetate (50 mL). Wash with 0.1 N aqueous citric acid, water, and saturated aqueous sodium chloride. Dry (magnesium sulfate), filter and concentrate. Purify on silica gel, eluting with 10:90 to 50:50 ethyl acetate:hexanes to give the title compound.
