実験手順

A mixture of 2-hydroxy-3,5-diiodobenzoic acid (3.9 g, 10.0 mmol) potassium carbonate (4.15 g, 30.0 mmol) and dimethyl sulfate (2.77 g, 22.0 mmol) in acetone (33 ml) was heated at reflux for 16 h, cooled and concentrated. The residue was dissolved in EtOAc and washed with water, brine, dried (Na2SO4), filtered and concentrated to give an off-white solid (4.2 g, quantitative yield).
