Procedure

A mixture of 1.1 g of methyl 2-(2-methylphenoxy)-3-methoxyacrylate, 0.95 g of N-bromosuccinimide, and a catalytic amount of azobisisobutyronitrile was heated at reflux in carbon tetrachloride for 4 hours. The solid was filtered, and the solvent evaporated to give a crude sample of methyl 2-(2-bromomethylphenoxy)-3-methoxyacrylate. A mixture of this crude sample together with 0.6 g of o-cresol, and 1.0 g of potassium carbonate was heated at reflux in acetonitrile for 20 hours. The solid was filtered, the solvent evaporated, and the residue purified by silica gel chromatography to give methyl 2-[2-(2-methylphenoxy)methylphenoxy]-3-methoxyacrylate (0.47 g).
