实验过程

A solution of the compound ([3]-(33)-587) (0.60 g) prepared in Example 37, ethanol (150 ml), and ethyl acetate (40 ml) was stirred at 70° C. for 15 minutes. After 10% Pd/C (0.10 g) and hydrazine monohydrate (1 ml) were added to the solution, the mixture was stirred at 70° C. for 1 hour. The insolubles were filtered through celite, and the filtrate was concentrated to obtain colorless foam (0.67 g). The product was purified by silica gel column chromatography (Kieselgel 60=80 g, chloroform/ethyl acetate=13/7) to obtain the compound ([3]-(34)-587) (0.09 g).
