실험 절차

After dissolving 2-[(1-tert-butoxycarbonyl-piperidin-4-ylmethyl)-amino]-1H-benzimidazole-4-carboxylic acid methyl ester (2.28 g, 5.87 mmol) in methanol (3 ml), a 4N hydrogen chloride-1,4-dioxane solution (10 ml, 40 mmol) was added and the mixture was stirred at room temperature overnight. The precipitated crystals were filtered out, washed with ethyl acetate and then dried to obtain 2-[(piperidin-4-ylmethyl)-amino]-1H-benzimidazole-4-carboxylic acid methyl ester. The compound was identified by LC-MS.
