실험 절차

400 mg of 1-{[1-(1-ethyl-propyl)-2-thiophen-2-ylmethyl-1H-benzoimidazole-5-carbonyl]-amino}-cycloheptanecarboxylic acid methyl ester were dissolved in 4 ml ethanol and 2 ml THF and 4 ml of 2 M aqueous sodium hydroxide solution were added. After stirring at room temperature over night, the reaction mixture was brought to pH 3 by addition of 2 M aqueous hydrochloric acid and extracted with ethyl acetate three times. The combined organic phases were dried over magnesium sulphate and concentrated to yield 100 mg (26%) of 1-{[1-(1-ethyl-propyl)-2-thiophen-2-ylmethyl-1H-benzoimidazole-5-carbonyl]-amino}-cycloheptanecarboxylic acid.
