Sodium Hydroxide → (1RS,2SR)-2-amino-1-(4-fluorophenyl)-3-(3-(trifluoromethyl)phenyl)-1-propanol

Participants

Reaction Steps

To a solution of (4RS,5SR)-5-(4-fluorophenyl)-4-((3-(trifluoromethyl)phenyl)methyl)-1,3-oxazolidin-2-one (4.0 g, 11.8 mmol) in ethanol (80 ml) was added 8N aqueous sodium hydroxide solution (7.4 ml, 59 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. The residue was recrystallized from ethyl acetate-hexane to give (1RS,2SR)-2-amino-1-(4-fluorophenyl)-3-(3-(trifluoromethyl)phenyl)-1-propanol (2.97 g, 80%).
