Procedure
1.12 g (7.5 mmol) of triethylenetetramine was added to 25 mL of dichloromethane and dissolved with stirring in an ice water bath at 5° C. for 30 minutes. To the solution, a solution of 2.00 g (6.0 mmol) of oleoyl chloride in 20 mL of dichloromethane in a separate reactor was added slowly dropwise while it was allowed to react at 5° C. for 3 hours. Due to hydrogen chloride produced during the reaction, unreacted triethylenetetramine HCl was precipitated. Before the end of the reaction, the upper layer solution was taken and analyzed by thin layer chromatography (TLC) with a mobile phase of ethanol:chloroform (2:1) to determine whether the reaction was completed. After it was determined that the reaction had completed, the precipitate was removed using filter paper.
