실험 절차

The compound (22) (130 mg) obtained in item (11) above was dissolved in methanol (6 ml), to which was added a 0.2M sodium methylate solution (0.5 ml) in methanol and the resulting mixture was allowed to stand at room temperature for 30 minutes. The reaction solution as formed was neutralized with addition of ion-exchange resin, Amberlite CG-120 (H+ form) (100-200 mesh), filtered and the filtrate was concentrated to give a solid material which was then washed with diethylether to afford the titled compound (23) (63 mg) as an insoluble substance. Yield: 60%.
