Catalytic conversion of 5-hydroxymethylfurfural into 2,5-furandiamidine dihydrochloride

Via implantation of nitrogen from aq. NH3 into hydroxymethylfurfural (HMF), dimethyl furan-2,5-dicarboximidate was synthesized over a manganese oxide catalyst. It was realized by the ammoxidation of HMF followed by methanol addition under mild reaction conditions. The imidate prepared in situ was further transformed into 2,5-furandiamidine dihydrochloride by reaction with ammonium chloride.
