실험 절차

5-[1-(4-benzyloxyindol-3-yl)ethyl]-2-dimethylamino-2-oxazolin-4-one (268 mg) was dissolved in a mixture of ethanol and tetrahydrofuran (7:3.10 ml). 10% palladium-carbon (80 mg) was added and the whole was hydrogenated for 5 hours at room temperature under normal pressure. The catalyst was removed from the mixture and 10% palladium-carbon (80 mg) was added again. The whole was hydrogenated for additional 24 hours at room temperature under normal pressure. The reaction mixture was filtered to remove the catalyst. The filtrate was concentrated to give 2-dimethylamino-5-[1-(4-hydroxyindol-3-yl)ethyl]-2-oxazolin-4-one (125 mg).
