Versuchsvorschrift

A mixture of 2-ethylphenol (244 mg) in acetonitrile (20 ml) was treated with cesium carbonate (650 mg) and ethyl bromoacetate (0.221 ml) and the mixture stirred at 60° C. for 6 hours and then at ambient temperature for 17 hours. The reaction mixture was diluted with ethyl acetate; the suspension filtered and the title compound isolated by evaporation in vacuo of the filtrate as a colourless oil.
