Procedure

A mixture of compound 34d (180 mg, 0.41 mmol), LiOH (39 mg, 1.62 mmol), THF (3 mL), MeOH (3 mL), and H2O (3 mL) was stirred at room temperature for 4 h. The mixture was acidified with 15% aqueous citric acid and extracted with EtOAc (3×). The combined organic extracts were washed with brine, dried over Na2SO4, filtered, and concentrated under reduced pressure. The resultant residue was dried under reduced pressure for 2 h to give compound 34e (166 mg).
