A solution of 5.37 g (62.4 mmol) of butanedione in 30 ml of acetonitrile is slowly added dropwise to a solution of 10.00 g (62.4 mmol) of commercial N,N′-bis (2-aminoethyl)-1,3-propanediamine in 100 ml of acetonitrile at 0° C. The mixture is maintained at this temperature for two hours. After evaporating the solvent, compound 1 is isolated quantitatively in the form of a yellow solid and is used for the following stage without subsequent purification.
