Versuchsvorschrift
A solution of the obtained N-[2-(1-adamantyl)ethyl]-N′-[3-(4-pyridyl)propyl]-1,3-propanediamine (80 mg, 0.23 mmol) in anhydrous methylene chloride (10 ml) and a solution of 1,1′-carbonyldiimidazole (40 mg, 0.26 mmol) in anhydrous methylene chloride (10 ml) were simultaneously added dropwise to anhydrous methylene chloride (60 ml) at room temperature with stirring over 20 minutes. The mixture was stirred overnight, then the reaction mixture was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography to give the target compound (8.0 mg, 9.4%).
