Procedure

In 5 ml of water was dissolved 0.148 g of the compound obtained in Example 7. To this solution were added 5 ml of a 0.1M phosphate buffer solution, 5 ml of ethanol and 0.075 g of 10% palladium-carbon. Into the mixture was introduced hydrogen gas while stirring under ice-cooling. In 1.5 hour after starting of the reaction, 0.04 g of 10% palladium-carbon was added to the reaction system, followed by stirring for further one hour. The catalyst was filtered off, and the filtrate was concentrated under reduced pressure to a volume of about 5 ml. The residue was subjected to a Amberlite XAD-2 column chromatography. Fractions eluted with water were combined and freeze-dried to give 0.091 g of the subject compound as powders.
