0.1122 g (5×10-4 mols) of palladium acetate, 6.61 ml (50 millimols) of p-tolyl chloride, 6.78 ml (62.5 millimols) of ethyl acrylate and 11.91 ml (50 millimols) of tri-n-butylamine in 100 ml of p-xylene are stirred for 3 hours at 120° C. The mixture is extracted by shaking with 50 ml of 2 N HCl, 25 ml of 2 N NaOH and 25 ml of water, and is then dried for 15 minutes with 5 g of magnesium sulphate. The crude product is distilled in vacuo. 6.08 g (64% of theory) are obtained as a colourless liquid. Analysis for C12H14O2 : calculated C 75.77%, H 7.52%; found C 75.73%, H 7.54%.
