실험 절차

A suspension of compound 52 (26.2 g, 124 mmol) and Pd/C (10 wt. %, 6.0 g) in THF (400 mL) and MeOH (200 mL) was stirred under an atmosphere of H2 at room temperature for 18 hours. EtOAc (300 mL) was added to the mixture and filtered through a Celite pad. The filtrate was concentrated in vacuo to provide the crude product 53 (22.4 g, 99%) as colorless oil.
