Reaction Steps
50.00 g (450 mmol) histamine are dissolved in 1500 ml dimethylformamide, 73.87 g (450 mmol) carbonyldiimidazole are added. The reaction mixture is stirred for 5 hours at 70° C. and for 16 hours at ambient temperature. Then the mixture is evaporated down, the residue is extracted hot from acetonitrile.
