실험 절차

45 g of 4-aminomethylpiperidine are placed in 500 ml of anhydrous toluene in the presence of 55 g of potassium carbonate and of 50 g of 2-chlorobenzimidazole. The mixture is subjected to reflux overnight. Aver evaporation and crystallization of the oily residue, the expected product is obtained after washing with dichloromethane.
