Procedure

The compound (516 mg, 0.42 mmol) synthesized in Example 6 (6i) was dissolved in methanol (6 mL) and toluene (6 mL) and sodium methoxide (221 μL, 1.15 mmol) was added thereto, followed by stirring of the mixture at 50° C. for 40 minutes. After cooling to room temperature, Dowex 50W×8 was added thereto until the reaction mixture became neutral and it was filtered, followed by distilling off of the solvent under reduced pressure. The residue was purified using silica gel flash column chromatography (hexane:diethyl ether, 1.5:1-1:1, v/v) to obtain the desired title compound (173 mg, yield 47%) as colorless amorphous matter.
