The compound (23) (52 mg) obtained in item (12) above was dissolved in methanol (6 ml), and the solution was subjected to catalytic reduction by blowing hydrogen therein in the presence of palladium black as catalyst at room temperature for 30 minutes. The resulting reaction solution was filtered and the filtrate was concentrated to give a solid. The solid material thus obtained was washed with ethyl acetate to yield the titled compound (24) (43 mg) as an insoluble substance. Yield: 89%.
