실험 절차
To tert-butyl 3-(4-ethoxy-4-oxobutyl)-4-oxo-1-phenyl-1,3,8-triazaspiro[4.5]decane-8-carboxylate (0.09 g, 0.2 mmol) was added 4M solution of HCl in dioxane (2 mL). After stirring at room temperature for 2 hours, the reaction mixture was concentrated in vacuo to obtain ethyl 4-(4-oxo-1-phenyl-1,3,8-triazaspiro[4.5]decan-3-yl)butanoate as a hydrochloride salt.
