Dimethylformamide → Ethyl 7-(2,4,6-triiodophenoxy)heptanoate

Participants

Reaction Steps

Dimethylformamide (DMF, 20 mL) was added with ethyl 7-bromoheptanoate (4.7 g) and 2,4,6-triiodophenol (2.4 g), further added with potassium carbonate (2.1 g) and stirred at room temperature for one day. The reaction solution was added with water and extracted twice with ethyl acetate, and the organic layer was washed three times with water and dried over anhydrous magnesium sulfate. Then, the solvent was removed, and the resulting residue was purified by silica gel column chromatography to obtain ethyl 7-(2,4,6-triiodophenoxy)heptanoate (6.0 g, yield: 96%).
