Benzyl 3-(3-(tert-butoxycarbonyl)benzyl)-1-(4-fluorophenyl)-4-oxo-1,3,8-triazaspiro[4.5]decane-8-carboxylate → Tert-butyl 3-((1-(4-fluorophenyl)-4-oxo-1,3,8-triazaspiro[4.5]decan-3-yl)methyl)benzoate

Participants

Reaction Steps

To a solution of benzyl 3-(3-(tert-butoxycarbonyl)benzyl)-1-(4-fluorophenyl)-4-oxo-1,3,8-triazaspiro[4.5]decane-8-carboxylate (0.82 g, 1.43 mmol) in methanol (10 mL), was added 10 wt % palladium on carbon (0.2 g). After stirring under hydrogen at room temperature and atmospheric pressure for 4 hours, the reaction mixture was filtered, washed with methanol, concentrated in vacuo to obtain tert-butyl 3-((1-(4-fluorophenyl)-4-oxo-1,3,8-triazaspiro[4.5]decan-3-yl)methyl)benzoate (0.62 g, 99%).
