実験手順
A solution of 0.6 g of 9-nitro-20(S)-camptothecin in 7.5 ml of DMF was hydrogenated at room temperature and atmospheric pressure in the presence of 0.02 g of 10% Pd/C for four hours. The catalyst was filtered off, and washed with warm DMF repeatedly. The solution was evaporated in vacuo and the crude reaction mixture was purified by column chromatography, to yield the title product.
