Procedure
A solution of 3-8 (1.86 mg, 0.32 mmol), LiOH.H2O (67 mg, 1.6 mmol), H2O (2 mL), and THF (8 mL) was stirred at ambient temperature for 1.0 h. The solution was acidified with 1M NaHSO4 followed by evaporation of THF. The residue was partitioned between EtOAc and brine. The EtOAc layer was then dried (MgSO4) and concentrated to give 3-9 as a pale yellow solid. Rf 0.40 (silica, 9/.0.5/0.5 CH2Cl2 :CH3OH:HOAc).
