실험 절차

After dissolving 2-[(piperidin-4-ylmethyl)-amino]-1H-benzimidazole-4-carboxylic acid methyl ester (20 mg, 0.055 mmol) in dimethylsulfoxide-acetic acid (10:1), 2-hydroxy-3,5-dichlorobenzaldehyde (32.0 mg, 0.166 mmol) and sodium triacetoxyborohydride (35.0 mg, 0.166 mg) were added and the mixture was stirred at 50° C. for 2 days. Methanol (1 ml) was added to the reaction mixture, and then after stirring for 1 minute, it was purified by SCX solid phase extraction (Bond Elute SCX500MG). The product was further purified by preparative HPLC to obtain 2-{[1-(3,5-dichloro-2-hydroxy-benzyl)-piperidin-4-ylmethyl]-amino}-1H-benzimidazole-4-carboxylic acid methyl ester. The compound was identified by LC-MS.
