Reaction Steps
To a solution of methyl 4-carboxy-3-methoxycinnamate (400 mg) in N,N-dimethylformamide were added methylamine hydrochloride (126 mg), I-ethyl-3-(3-dimethylaminopropyl)-carbodiimide hydrochloride (390 mg) and 1-hydroxybenzotriazole (320 mg) at ambient temperature, and the mixture was stirred for 18 hours at the same temperature. The reaction mixture was poured into water and extracted with ethyl acetate. The organic layer was washed with water, saturated sodium bicarbonate solution and brine, dried over magnesium sulfate and evaporated in vacuo. The residue was purified by column chromatography on silica gel (chloroform: methanol=40:1, v/v) to give methyl 3-methoxy-4-(methylcarbamoyl)cinnamate (319 mg).
