実験手順

A solution of 5-[4-(4-(2-amino-2-methoxycarbonylethyl)phenoxy)benzyl]thiazolidin-2,4-dione hydrochloride (2.03 g, 4.65 mmol) and N-t-butoxycarbonylpyrrolidin-2-carboxylic acid (1 g, 4.65 mmol) in N,N-dimethylformamide (20 ml) was stirred for 1 h at 0° C. N,N′-Dicyclohexylcarbodiimide (0.96 g, 4.65 mmol) was added to this solution and stirring was continued for 2 h at ambient temperature. Water (150 ml) was added to the reaction mixture, stirred for 20 minutes, ethyl acetate (200 ml) was added and stirring continued for another 15 minutes. The organic layer was separated and washed with water (100 ml), dried over anhydrous sodium sulfate and concentrated to give the crude compound, which was purified by column chromatography (1.42 g, yield 51.2%).
