실험 절차

A 4 N HCl solution in dioxane (6 mL) was added to a solution of tert-butyl 4-(2-oxo-2-(piperidin-1-yl)ethoxy)piperidine-1-carboxylate (111) (7.5 g, 22.98 mmol) in MeOH (20 mL) and the reaction mixture was stirred at room temperature for 6 hours. Removal of solvent afforded 1-(piperidin-1-yl)-2-(piperidin-4-yloxy)ethanone as its hydrochloride salt (2.300 g, 44.2%). This salt was then dissolved in methanol (50 ml) and MP-carbonate (14.88 g, 33.61 mmol) was added. The resulting mixture was filtered and the solvent removed to give the desired compound (2.300 g, 44.2%), which was used without further purification.
