Procedure

1 mol of 2-methyl-1,5-diaminopentane was slowly added dropwise, under a nitrogen atmosphere, to 2 mol of diethyl maleate, in such a manner that the reaction temperature did not exceed 60° C. Heating was then carried out at 60° C. until no further diethyl maleate could be detected in the reaction mixture. The product was obtained quantitatively in the form of a yellow liquid.
