Versuchsvorschrift

0.5 g (1.4 mmol) of 3-(1-trityl-1H-imidazol-4-yl)propylamine is dissolved in 8 mL of dichloromethane with 2 mL of trifluoroacetic acid. After 2 hours, the medium is concentrated. The beige-coloured solid obtained is taken up in EtOAc and water, and the aqueous phase is then concentrated to dryness. 0.3 g of 4-(3-aminopropyl)-1H-imidazol-1-ium bis(trifluoroacetate) is obtained in a yield of 61%.
