Procedure

Into 45 mL of methanol was dissolved 954 mg of Compound 69, and 4.0 mL of 1 mol/L sodium hydroxide was added thereto. After 20 minutes of stirring under heating and refluxing, the solvent was removed by evaporation under reduced pressure, and the resulting residue was extracted with ether-water (1/1). To the aqueous layer was added 2 mol/L hydrochloric acid, and the precipitated crystals were washed with ether to obtain 746 mg of the title compound as colorless powder.
