11 1,6-Di-(N3-cyano-N1-guanidino)hexane
A solution of 3.78 g (20.0 mmol, 1 equiv) 1,6-hexamethylenediamine dihydrochloride and 3.56 g (40.0 mmol, 2 equiv) sodium dicyanamide in 28 mL n-butanol was heated to reflux for 8 h.
After cooling to room temperature, the solid was filtered off and washed with butanol and cold water.
Recrystallization from water afforded pure compound 3. Yield: 80%.
Melting point: 195 °C (Ref.: 202-203 °C).
