실험 절차

1H-Benzimidazole-2-carboxaldehyde (781 mg, can be prepared according to Fegy, K. Angewandte Chemie Int Ed, 1998, vol. 37, 1270-1273), 4-amino-1-methylpiperidine (781 mg) and 4 Å molecular sieves (15 g) in ethanol (100 mL) are heated under reflux for 4 h. The mixture is then filtered and the filtrate concentrated under reduced pressure to yield (1H-benzimidazol-2-ylmethylene)(1-methylpiperidin-4-yl)amine as a beige solid.
