Methoxyacetic Acid → Ethyl 4-(methoxyacetamido)cinnamate

Participants

Reaction Steps

To a solution of ethyl 4-aminocinnamate (2.00 g) and methoxyacetic acid (1.04 ml) in N,N-dimethylformamide (20 ml) were added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (2.61 and 1-hydroxybenzotriazole (2.12 g) at ambient temperature, and the mixture was stirred for 1 hour at the same temperature. The reaction mixture was poured into water, and extracted with dichloromethane. The organic layer was washed with aqueous sodium bicarbonate solution and water, dried over magnesium sulfate, and evaporated in vacuo. The residue was crystallized from diisopropyl ether to give ethyl 4-(methoxyacetamido)cinnamate (2.34 g) as a pale yellow powder.
