Versuchsvorschrift

An ethanol solution (20 ml) containing the compound (40.2 mg) obtained in Example 19-2 was added with an ethanol suspension of Raney nickel and a 1 mol/l sodium hydroxide aqueous solution (2.0 ml), and the whole was stirred at room temperature for 14 hours under a hydrogen atmosphere. The catalyst was removed by filtration through Celite. The residue obtained by distilling the solvent off under reduced pressure was dissolved in chloroform, washed with water and a saturated saline solution, and dried with anhydrous sodium sulfate. The solvent was distilled off, thereby obtaining the subject compound (40.1 mg) as a yellow oily substance.
