After cooling on ice again, 2N hydrochloric acid was added and extracted with chloroform. The chloroform layer was washed with water, dried over anhydrous sodium sulfate, and then concentrated to dryness under reduced pressure. The obtained solid was recrystallized from ethanol to obtain 0.18 g (yield: 42%) of the target compound "Compound No. 36" as pale brown crystals.
