Procedure

The compound (363 mg, 0.32 mmol) synthesized in Example 6 (6j) was dissolved in methanol (8 mL) and 1N aqueous potassium hydroxide solution (4 mL) was added thereto, followed by stirring of the mixture at 80° C. for 8 hours. After cooling to room temperature, saturated aqueous ammonium chloride solution (15 mL) was added to the reaction mixture and the mixture was extracted with ethyl acetate (100 mL). After the organic layer was washed with saturated brine (10 mL) and 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, 1.5:1-1:1, V/V) to obtain the desired title compound (313 mg, yield 91%) as pale yellow amorphous matter.
