Reaction Steps

To tert-butyl 3-(3-(benzyloxycarbonyl)benzyl)-4-oxo-1-phenyl-1,3,8-triazaspiro[4.5]decane-8-carboxylate (2.7 g, 4.86 mmol) was added 4M solution of HCl in dioxane (7 mL). After stirring at room temperature for an hour, the reaction mixture was concentrated in vacuo to obtain benzyl 3-((4-oxo-1-phenyl-1,3,8-triazaspiro[4.5]decan-3-yl)methyl)benzoate as a hydrochloride salt.
