Procedure
methyl 2″-({(4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-4-methyl-2-oxo-1,3-oxazolidin-3-yl}methyl)-4′,6′-difluoro-2-methyl-4″-(trifluoromethyl)-1,1′:3′,1″-terphenyl-4-carboxylate (73.5 mg, 0.10 mmol), lithium hydroxide monohydrate (42 mg, 1 mmol), water (1 mL) and 1,4-dioxane (2 mL) were stirred at room temperature for 2 hrs. Volatiles were removed under reduced pressure. Pot residue was dissolved in a MeCN/1N HCl (aq) mixture and purified by reverse-phase prep-HPLC (Kromasil 100-5C18, 100×21.1 mm) eluting w/a MeCN (0.1% TFA, v/v)/H2O (0.1% TFA, v/v) gradient mixture. Corresponding fractions were pooled & evaporated in vacuo to afford the title compound.
