2,5-Bis(aminomethyl)furan as a promising monomer was efficiently synthesized in 94.1% yield from biomass-derived 2,5-diformylfuran dioxime. The high selectivity is likely to be a result of the controlled reaction pathway over Rh/HZSM-5, which enhanced the sequence of the dehydration-hydrogenation of 2,5-diformylfuran dioxime owing to the surface acidity on the HZSM-5 support.

PROBLEM TO BE SOLVED: To provide a method for stably supplying 2,5-bis(aminomethyl)furan. SOLUTION: In synthesizing 2,5-bis(aminomethyl)furan by the hydrogenation reaction of fran-2,5,-dioxime, by preliminarily adding two equivalents or more of a hydrohalic acid, the hydrohalic acid reacts simultaneously with hydrogenation so that 2,5-bis(aminomethyl)furan dihydrohalide is obtained with high selectivity, and further the diamine can be easily supplied by adding a base to the dihydrohalide.
