The compound (40) (35 mg) obtained in item (7) above was dissolved in methanol (3.5 ml) and the resulting solution was subjected to catalytical reduction by blowing hydrogen therein in the presence of palladium black as catalyst at room temperature for 30 minutes. The reaction solution was filtered and the filtrate was concentrated. The resulting solid was washed with ethyl acetate to yield the titled compound (41) (29.7 mg) as an insoluble solid. Yield: 92%.
