Procedure

After dissolving 4-amino-2-{[1-(3,4-dichloro-benzyl)-piperidin-4-ylmethyl]-amino}-benzimidazole-1-carboxylic acid tert-butyl ester (10 mg, 0.02 mmol) in methanol (1 ml), a 4N hydrogen chloride-1,4-dioxane solution (1 ml) was added and the mixture was stirred at 50° C. for 1 hour. The reaction mixture was passed through SCX (Bond Elute SCX500MG), the SCX was washed with methanol, and then elution was performed with a 2N ammonia-methanol solution. The solvent was distilled off under reduced pressure to obtain N2-[1-(3,4-dichlorobenzyl)-piperidin-4-ylmethyl]-1H-benzimidazole-2,4-diamine. The compound was identified by LC-MS.
