実験手順
To a solution of 176 mg (0.32 mmol) of 2-(((S)-3-acetylthiazolidin-4-carbonyl)amino)-3-((3-methyl-4-oxo-1-phenyl-1,3,8-triazaspiro[4.5]decane-8-carbonyl)amino)propionic acid methyl ester in 4 ml of tetrahydrofuran, 4 ml of 0.1M aqueous lithium hydroxide solution was added, and the resulting mixture was stirred overnight at room temperature. To the reaction mixture, 0.1M hydrochloric acid was added, and the resulting mixture was extracted with ethyl acetate. Organic phases were combined, washed with saturated saline, dried over anhydrous sodium sulfate, and concentrated. The residue was reprecipitated from ether/chloroform to obtain 130 mg of 2-(3-acetylthiazolidine-4-carbonyl)amino)-3-((3-methyl-4-oxo-1-phenyl-1,3,8-triazaspiro[4.5]decane-8-carbonyl)amino)propionic acid (yield: 76%).
