Sodium Iodide → 2-Benzo[1,3]dioxol-5-ylmethyl-3-oxo-3-phenylpropionate ethyl ester

Participants

Reaction Steps

5-Chloromethyl benzo[1,3]dioxol (11.2 g, 65.7 mmol) was dissolved in Dimethylformamide. Then, potassium carbonate (18.2 g, 131.4 mmol), sodium iodide (10.8 g, 72.27 mmol) and ethyl benzoylacetate (12.5 ml, 72.27 mmol) were added thereto and stirred for 5 hours at room temperature. The reaction mixture was extracted with ammonium chloride and ether, the organic layer was separated, dried over anhydrous magnesium sulfate, concentrated, and the resulting residue was purified by column chromatography to obtain 2-benzo[1,3]dioxol-5-ylmethyl-3-oxo-3-phenylpropionate ethyl ester (16.4 g, 76%).
