Reaction Steps

9 mg of compound (34) was dissolved in 2 ml of ethyl acetate and allowed to react in the presence of a catalytic amount of 10% palladium-carbon under stirring under a hydrogen atmosphere at room temperature for 2 hours. The reaction solution was filtered, and the filtrate was concentrated in vacuo. The reaction product was charged onto a silica gel column (Kieselgel 60, Merck, 1.0φ×30 cm) and eluted with chloroform-methanol (30:1). The fraction containing the desired product was concentrated to dryness to give 6.8 mg of compound (35).
