Reaction Steps

After dissolving 4-{[4-(2-methoxy-ethylcarbamoyl)-1H-benzimidazol-2-ylamino]-methyl}-piperidine-1-carboxylic acid tert-butyl ester (1.30 g, 3.01 mmol) in methanol (1 ml), a 4N hydrogen chloride-1,4-dioxane solution (7.0 ml, 28.0 mmol) was added and the mixture was stirred at 50° C. for 1 hour. The reaction mixture was concentrated under reduced pressure and vacuum dried to obtain 2-[(piperidin-4-ylmethyl)-amino]-1H-benzimidazole-4-carboxylic acid (2-methoxy-ethyl)-amide. The compound was identified by LC-MS.
