実験手順

To a solution of 2-[(1-Methyl-piperidin-4-yloxy)-(3-nitro-phenyl)-methyl]-1H benzimidazole (110 mg) in ethanol (5 mL) is added Tin(II)dichloride-dihydrate (340 mg). The reaction mixture is heated at reflux for 2 hours. Water is added to the mixture as well as sodium hydroxide 1N solution to pH 10 The solution is extracted with chloroform. The pooled organic phases are dried with magnesium sulphate and concentrated under reduced pressure. The residue is purified by chromatography (gradient dichloromethane/methanol/ammonia from 98/2/0.2 to 90/10/1) to give 3-[(1H-benzimidazol-2-yl)(1-methylpiperidin-4-yloxy)methyl]phenylamine that is used without further purification.
