Reaction Steps

To 1,1-dimethylethyl(4RS,5RS)-5-(6-chloro-2-pyridyl)-2-oxo-4-((4-(trifluoromethyl)phenyl)methyl)-1,3-oxazolidine-3-carboxylate (677 mg, 1.46 mmol) in methanol (3.5 ml) was added 0.5N sodium hydroxide methanol solution (3.5 ml, 1.75 mmol) under ice-cooling, and the mixture was stirred at room temperature for 1 hr. To the reaction solution was added water (50 ml), and the mixture was extracted with ethyl acetate (50 ml×2). The extract was washed with saturated brine, dried over anhydrous magnesium sulfate and evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate) and recrystallized from diisopropyl ether-hexane to give the title compound (550 mg, 57%).
