Procedure

Ester 6-3 (400 mg, 0.84 mmol) was dissolved in 4 mL EtOH, then 1 N NaOH (1.7 mL, 1.7 mmol) was added. After 90 min the reaction was neutralized with 1 N HCl (1.7 mL, 1.7 mmol) and concentrated to an oil. Flash chromatography (silica, 50:1:1 EtOH/H2O/NH4OH, then again with 12:10:1:1 EtOAc/EtOH/H2O/NH4OH) provided 6-4.
