실험 절차

To a solution of 331 mg (0.85 mmol) of 2-amino-3-((3-methyl-4-oxo-1-phenyl-1,3,8-triazaspiro[4.5]decane-8-carbonyl)amino)propionic acid methyl ester in 8.5 ml of dichloromethane, 149 mg (0.85 mmol) of (S)-3-acetylthiazolidin-4-carboxylic acid, 376 mg (0.85 mmol) of BOP reagent and 0.16 ml (0.95 mmol) of N,N-diisopropylethylamine were added, and the resulting mixture was stirred overnight at room temperature. To the reaction mixture, 10 ml of semi-saturated saline was added, and the resulting mixture was extracted with ethyl acetate. Organic phases were combined, washed with 0.5M hydrochloric acid, with saturated aqueous sodium hydrogen carbonate solution and with saturated saline, dried over anhydrous sodium sulfate, and concentrated. The residue was purified by silica gel column chromatography (chloroform:methanol=100:1-10:1) to obtain 305 mg 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 (yield: 65%).
