Procedure

5 mmol of 3-(1H-imidazol-4-yl)propanamine dihydrochloride and 10 mmol of triethylamine are mixed in 10 ml of acetonitrile and, after addition of 5 mmol of benzyl isocyanate, the whole mixture is brought to boiling for 1 h at reflux. After evaporation under vacuum, the title compound is taken up in a small amount of water and recrystallized in the hydrogenmaleate form from ethanol/diethyl ether.
