Procedure

Methyl 2″-({(4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-4-methyl-2-oxo-1,3-oxazolidin-3-yl}methyl)-4′-methoxy-4″-(trifluoromethyl)-1,1′:3′,1″-terphenyl-4-carboxylate (10 mg, 0.014 mmol), aqueous potassium hydroxide (150 μL, 3M, 0.45 mmol) and ethanol (1 mL) were stirred at 20° C. for 2 hours and 30 minutes to complete the hydrolysis. The reaction mixture was acidified by HCl (aq., 1N) and then basified by sodium bicarbonate. Volatiles were removed under reduced pressure. The resulting mixture was worked up with ethyl acetate, washed with brine. The combined organic extracts were dried over Na2SO4, filtered, and concentrated to an oil. This oil was purified by preparative TLC on SiO2 (eluted with 50% EtOAc in hexanes) to afford 2″-({(4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-4-methyl-2-oxo-1,3-oxazolidin-3-yl}methyl)-4′-methoxy-4″-(trifluoromethyl)-1,1′:3′,1″-terphenyl-4-carboxylic acid.
