Procedure

Ester 9-3 (44 mg, 0.1 1 mmol) was dissolved in 1.1 mL THF, then 1 N LiOH (0.28 mL, 0.28 mmol) was added. After stirring overnight the reaction mixture was loaded directly onto a flash chromatography column (silica, eluting with 7:20:1:1 EtOAc/EtOH/H2O/NH4OH) providing 9-4 as a white solid.
