Procedure
To a solution of (1S,2S) and (1R,2R)-3-(2-(4-chlorophenyl)-2′-oxospiro[cyclopropane-1,3′-indoline]-1′-yl)-5-(2-oxooxazolidin-3-yl)benzoate (43 mg, 0.088 mmol) in MeOH (2 mL) and H2O (0.2 mL) was added lithium hydroxide (18 mg, 0.44 mmol). The reaction mixture was stirred at room temperature until TLC indicated no further reaction. The methanol was removed under reduced pressure. After quenching with concentrated HCl (3.0 N), the mixture was extracted with ethyl acetate for three times. The organic layers were dried over anhydrous Na2SO4 and concentrated to give the crude product. Purification by preparative HPLC gave desired product as white solid (29 mg, 70%).
