Participants

Reaction Steps

To a solution of thiophen-3-acetic acid (8.7 g) in dichloromethane (70 mL) was added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (11.7 g), and the mixture was stirred for 10 minutes at room temperature. To the solution was added dropwise a solution of methyl 2-(2-oxopropylamino)isobutyrate (10.6 g) in dichloromethane (10 mL) at room temperature, and the mixture was then stirred for 24 hours at room temperature. After distilling off the solvent, water was added, and then the mixture was extracted with ethyl acetate. The extract was washed with a saturated sodium hydrogencarbonate aqueous solution and dried over anhydrous sodium sulfate. After distilling off ethyl acetate, 7.61 g of methyl 2-[N-(2-oxopropyl)thiophene-3-yl-acetylamino]isobutyrate was obtained.
