Procedure

3-Cyclopentyl propionylchloride (5 mmol) in 10 ml of dioxane was added dropwise to a solution of 10 mmol of 1-(3-aminopropyl)pyrrolidine in water. After stirring for 4 hours the solvent was evaporated under reduced pressure and the residue purified by column chromatography on silica gel (eluent: methylene chloride/methanol/aqueous ammonia (90/10/1)). The solvent was removed under reduced pressure and the residue was crystallized with oxalic acid from diethyl ether/ethanol.
