After adding 1-methyl-1H-indole-2-carboaldehyde (0.26 mmol) and sodium triacetoxyborohydride (0.26 mmol) to a solution of (1H-benzimidazol-2-yl)-piperidin-4-ylmethyl-amine (20.0 mg, 0.09 mmol) in dimethylformamide-acetic acid (10:1) (1.0 ml), the mixture was stirred at room temperature overnight. Methanol (1.0 ml) was added to the reaction mixture to suspend the reaction, and after stirring for 1 hour, the solution was passed through SCX (Bond Elute SCX500MG: cationic ion-exchange resin, Varian). The SCX was washed with methanol and then with a mixed solution of chloroform/methanol (1/1), and elution was performed with a 2N ammonia-methanol solution. The solvent was distilled off under reduced pressure to obtain (1H-benzimidazol-2-yl)-[1-(1-methyl-1H-indol-2-ylmethyl)-piperidin-4-ylmethyl]-amine. The compound was identified by LC-MS.
