실험 절차

Dissolve 4-(R)-[1-(S)-benzyloxy-3-(3-benzyloxyphenyl)-2-(S)-dibenzylaminopropyl]-2,2-dimethyloxazolidine-3-carboxylic acid tert-butyl ester (16.01 g, 22.0 mmol) in 4 M hydrogen chloride in 1,4-dioxane (130 mL) and stir for 30 minutes. Add water (65 mL) and stir for 18 hours. Slowly add sodium bicarbonate (50 g) and water (˜50 mL). Extract with ethyl acetate, wash with saturated aqueous sodium chloride, dry (magnesium sulfate), filter and concentrate to give the crude desired compound.
