Versuchsvorschrift

To an AcOEt (1 ml) solution of the compound (0.146 g) obtained in Example 19-(5), 4N HCl-AcOEt (0.5 ml) was added and the mixture was stirred at room temperature for 12 hours. After adding 4N HCl-AcOEt (0.5 ml) and stirring for 3 hours, 4N HCl-AcOEt (0.5 ml) was further added and stirring was continued for an hour. After adding an aqueous solution of 2N NaOH and performing extraction with AcOEt, the organic layer was washed with brine, dried (MgSO4), filtered and concentrated to give the titled compound (0.078 g, pale yellow solid.)
