Procedure
27 g of 4-aminomethylpiperidine are placed in 300 ml of anhydrous toluene in the presence of 33 g of potassium carbonate and of 33 g of 1-methyl-2-chlorobenzimidazole. The mixture is subjected to reflux for 48 hours. After evaporation, the residue is taken up in ether and an excess of hydrochloric ether. The precipitate formed is spun down, washed with ether, and then taken up in 750 ml of water and 30% caustic soda is added to give a basic pH.
