Reaction Steps

THF (400 μL) and water (400 μL) were added to an acetic acid solution (800 μL) of the compound (151 mg, 0.259 mmol) produced in Example 15, and the mixture was stirred at 60° C. for 3 hours and 30 minutes. The reaction solution was concentrated under reduced pressure, and purified with a column apparatus (Hiflash-SI, Size S, ethyl acetate:hexane=1:1→ethyl acetate) manufactured by Yamazen Corporation to obtain a titled compound (74 mg) having the following physical property values. TLC: Rf 0.28 (dichloromethane:methanol=20:1);
