実験手順

A solution of 3-{[2-(acetylamino)ethylthio]methyl}-4-oxo-4-(3-pyridyl)butanoic acid (0.1 g), 1[3-(dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride (68.1 mg) and 4-dimethylaminopyridine (0.1 eq) in dimethyl formamide (2 mL) was stirred for 24 h. The solution was purified on preparative HPLC (C-18 prep column, 10% to 90% acetonitrile in water both containing 0.1% TFA) to give 0.085 g (75%) of the title compound; ESMS (M+1)+353.
