Reaction Steps

To a solution of benzyl 3-(3-(methylsulfonamido)benzyl)-4-oxo-1-phenyl-1,3,8-triazaspiro[4.5]decane-8-carboxylate (0.82 g, 1.49 mmol) in methanol (15 mL), was added 10 wt % palladium on carbon (0.15 g). After stirring under hydrogen at room temperature and atmospheric pressure for 18 hours, the reaction mixture was filtered, washed with methanol, concentrated in vacuo to obtain N-(3-((4-oxo-1-phenyl-1,3,8-triazaspiro[4.5]decan-3-yl)methyl)phenyl)methanesulfonamide (0.62 g, 99%).
