실험 절차

To a solution of the compound obtained from step g above (0.8 g) in ethyl acetate (15 mL), 10% palladium on charcoal (0.25 g) was added at room temperature. The system was evacuated with hydrogen and the reaction mixture was stirred for 4 hours at room temperature under a hydrogen atmosphere. The reaction mixture was filtered through a celite pad, and concentrated to afford the title compound (0.75 g).
