実験手順
To a solution of 2-{[(4-tert-Butoxycarbonylamino-butyl)-(3-methyl-pyridin-2-ylmethyl)-amino]-methyl}-benzoimidazole-1-carboxylic acid tert-butyl ester (0.82 g, 1.57 mmol) in EtOH (8 mL) was added anhydrous hydrazine (0.50 mL, 15.9 mmol) and the resultant mixture was stirred at room temperature overnight. The mixture was filtered through filter paper and concentrated. Purification of the crude material by column chromatography on silica gel (20:1:1 CH2Cl2-MeOH—NH4OH) provided 0.42 g (62%) of {4-[(1H-benzoimidazol-2-ylmethyl)-(3-methyl-pyridin-2-ylmethyl)-amino]-butyl}-carbamic acid tert-butyl ester as white solid.
