Versuchsvorschrift

The compound (1.22 g) obtained in Example 44-2 was dissolved in THF (12.2 ml) and added with 1 mol/l hydrochloric acid (12.2 ml). The whole was stirred at room temperature for 19 hours. The reaction solution was concentrated under reduced pressure. The residue was added with a 1 mol/l sodium hydroxide aqueous solution and the whole was subjected to extraction with chloroform. The organic layer was washed with a saturated saline solution and dried with anhydrous sodium sulfate, followed by concentration under reduced pressure. The residue was purified through silica gel column chromatography (chloroform/methanol), thereby obtaining the subject compound (0.790 g) as a yellow oily substance.
