実験手順
tert-Butyl (S)-6-(4-(2-((tert-butoxycarbonyl)amino)-3-oxo-3-(piperidin-1-yl)propyl)phenyl)hex-5-ynoate (Compound SP425) (5.74 g, 11.51 mmol) was dissolved in ethyl acetate (40 ml), and 10% palladium(II) on carbon (1.72 g) was added under a nitrogen atmosphere. The mixture was then stirred at room temperature for 2 hours under a hydrogen atmosphere. After filtration through celite, the filtrate was concentrated under reduced pressure to afford the title compound SP426 (5.65 g, 98%).
