Water → Methyl 3-(3,4-dichlorophenyl)prop-2-enoate

Participants

Reaction Steps

To a solution of 3,4-dichlorocinnamic acid (21.7 g) and cesium carbonate (22.8 g) in DMF (200 mL) was added methyl iodide (7.47 mL) at 0° C., and the mixture was stirred at room temperature for 12 hr. The reaction mixture was poured into water, and the resultant product was extracted with ethyl acetate. The organic layer was washed with saturated aqueous sodium hydrogen carbonate solution, water, 1M KHSO4 solution and brine and dried, and the solvent was evaporated under reduced pressure to give methyl 3,4-dichlorocinnamate (22.4 g, 97%) as a white powder.
