Versuchsvorschrift
A mixture consisting of 49.0 g (248 mmol) of ethyl 5-(dimethylaminomethyl)-2-furancarboxylate and 150 g (2.496 mol) of anhydrous ethylenediamine was heated at 80° C. for 2 hours. After cooling, the excess ethylenediamine was distilled off under reduced pressure to give 54.8 g (98.0%) of 5-(dimethylaminomethyl)-N-(2-aminoethyl)-2-furancarboxamide (Compound a) as light yellow oil.
