Abstract: A synthetic procedure for the synthesis of diamino difurfuryl compounds via a one-step, low-temperature reaction that does not require additional steps for the protection of the amino functionalities in the reactant or the deprotection of the amino functionalities in an intermediate product to give the final product is disclosed. The importance of acid concentration, reaction temperature, and reaction time to the one step method are disclosed.
