Procedure

To a solution of the compound (33.1 g, 62.0 mmol) obtained in Example 60-4) in tetrahydrofuran (500 mL), tetrabutylammonium fluoride (74.4 mL, 1 M tetrahydrofuran solution) was added, and the mixture was stirred at room temperature for 1.5 h. Saturated aqueous sodium hydrogencarbonate was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated sodium chloride solution and then dried with anhydrous sodium sulfate, and the solvent was distilled off under reduced pressure. The concentrated residue was purified by silica gel column chromatography (ethyl acetate:methanol=4:1) to obtain the title compound (22.5 g, 87%) as a white solid.
