実験手順
100 mg (0.2 mM) of the compound obtained in Example 1 was dissolved in 1 ml of methanol to which 0.3 ml (0.3 mM, 1.5 eq) of 1N sodium hydroxide was added dropwise, and the resulting mixture was heated with stirring under a nitrogen atmosphere for 1 hour. The resultant was acidified with 1N hydrochloric acid solution, and extracted with ethyl acetate and brine. The organic solvent layer was dried over anhydrous sodium sulfate, filtered, and then distilled under reduced pressure, to obtain 90 mg (91.5%) of the title compound.
