実験手順

A solution of 43A (3.35 g, 11.7 mmol) in MeOH (30 mL):EtOAc (30 mL) was degassed with argon for 30 minutes. The resulting solution was treated with 10% Pd/C (335 mg) and stirred under a hydrogen atmosphere for 2 hours. The reaction mixture was filtered through a pad of celite and concentrated to afford 43B (2.6 g, 87%).
