Ethanol → Ethyl 2-acetyl-4-methylpent-4-enoate

Participants

Reaction Steps

In a reaction vessel of 1.5 l equipped with a mechanical stirrer, a condenser, a thermometer and an inlet tube for nitrogen, 600 g (4.61M) of ethyl acetate, 375.9 g (4.15M) of methallyl chloride, 500 ml of ethanol and 636.9 g (4.61M) of potassium carbonate are mixed together. The resulting suspension is heated at reflux for 2 h while the mixture becomes slightly yellow and thick. Ethanol is stripped off and the obtained residue is dissolved in 900 ml of water. The two layers thus formed are separated and the organic phase is washed with 900 ml of water.
