Procedure

The compound (1.57 g, 1.70 mmol) synthesized in Example 19 (19a) was dissolved in methanol (30 mL) and potassium carbonate (235 mg, 1.70 mmol) was added thereto, followed by stirring of the mixture at room temperature for 14 hours. The reaction mixture was diluted with ethyl acetate (10 mL) and the mixture was washed with saturated aqueous sodium hydrogencarbonate (10 mL) and saturated brine (10 mL). After the organic layer was dried with anhydrous sodium sulfate, the solvent was distilled off under reduced pressure. The residue was purified using silica gel flash column chromatography (hexane:ethyl acetate, 3:1, V/V) to obtain the desired title compound (1.41 g, 94.0%) as a colorless oil.
