Difurfuryl diamino compounds can be obtained via single-step reactions of furfurylamine with formaldehyde and other aldehydes in 2.5-5.2 M hydrochloric acid at 20-50 degrees C. Yields for the single step reaction (30-50%) are comparable to those for three-step procedures involving protection and deprotection of the amino group.
