Versuchsvorschrift

In an Emrys Optimizer microwave reactor, 0.8 g (2 mmol) of (Z)-3-(3-butoxy-4-iodophenyl)-2-ethoxyacrylic acid is dissolved in 10 mL of methanol and 1 mL of concentrated sulfuric acid and heated at 70° C. by microwave for 2 hours. After addition of water, the reaction medium is extracted with ethyl acetate. The organic phase is washed with water, dried over magnesium sulfate, filtered and evaporated. 0.5 g (61%) of methyl (Z)-3-(3-butoxy-4-iodophenyl)-2-ethoxyacrylate is obtained.
