実験手順

To a solution of (4RS,5SR)-5-(4-fluorophenyl)-4-{3-[(trifluoromethyl)thio]benzyl}-1,3-oxazolidin-2-one (1.30 g, 3.50 mmol) in ethanol (3 ml) was added 8N aqueous sodium hydroxide solution (1.31 ml,10.5 mmol), and the mixture was stirred at 80° C. for 4 hrs. To the reaction solution was added water (20 ml), and the mixture was extracted with ethyl acetate (50 ml×2). The extract was washed with water and saturated brine, dried (anhydrous magnesium sulfate) and evaporated under reduced pressure to give the objective substance (0.8 g, 77%).
