実験手順
To a solution of (4RS,5SR)-5-(4-phenoxyphenyl)-4-((4-(trifluoromethyl)phenyl)methyl)-1,3-oxazolidin-2-one (6.0 g, 14.5 mmol) in ethanol (100 ml) was added 8N aqueous sodium hydroxide solution (9.0 ml, 72 mmol), and the mixture was heated under reflux for 4 hrs. The reaction solution was concentrated and diluted with water (300 ml). The mixture was extracted with ethyl acetate (300 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-phenoxyphenyl)-3-(4-(trifluoromethyl)phenyl)-1-propanol (5.03 g, 90%).
