To a solution of the compound obtained in Example 30 (2) (0.3586 g) in ethanol (8 ml), acetic acid (1 ml) and 10% palladium carbon (0.3586 g) were added and the mixture was stirred at 50° C. for 15 hours under hydrogen atmosphere. The reaction solution was filtered. The filtrate was concentrated under reduced pressure. The resulting residue was separated using silica gel column chromatography (hexane:ethyl acetate=1:1) to obtain 0.183 g of the desired product.
