Participants

Reaction Steps

To a solution of (4RS,5SR)-5-(4-((4-chloro-3-ethylphenyl)oxy)phenyl)-4-((3-((1,1,2,2-tetrafluoroethyl)oxy)phenyl)methyl)-1,3-oxazolidin-2-one (4.3 g, 8.21 mmol) in ethanol (20 ml) was added 8N aqueous sodium hydroxide solution (5.13 ml, 41.1 mmol), and the mixture was heated under reflux for 4 hrs. The reaction solution was concentrated, diluted with water (100 ml), and extracted with ethyl acetate (100 ml×2). The extract was washed with saturated brine, dried over anhydrous magnesium sulfate and evaporated under reduced pressure to give (1RS,2SR)-2-amino-1-(4-((4-chloro-3-ethylphenyl)oxy)phenyl)-3-(3-((1,1,2,2-tetrafluoroethyl)oxy)phenyl)-1-propanol (3.64 g, 89%) as a colorless oil.
