실험 절차

Combine 2-chloro-1H-benzimidazole (5.0 g, 33 mmol) and 1-benzyl-4-aminopiperidine (14.2 g, 75 mmol) and heat to about 150° C. After 12 hours, cool and partition between water and chloroform, warming if necessary. Separate the layers and add methanol and toluene to the organic layer. Evaporate the organic layer in vacuo to give a solid. Triturate the solid with ethyl acetate, collect by filtration, and dry to give (1H-benzimidazol-2-yl)(1-benzylpiperidin-4-yl)amine: Rf=0.30 (2% triethylamine/10% methanol/ethyl acetate).
