Procedure
A solution of 3-bromophenylacetone (50.0 g, 235 mmol), methyl acrylate (40.4 g, 469 mmol), palladium(II)acetate (7.9 g, 35.2 mmol), tri-ortho-tolylphosphine (21.4 g, 70.4 mmol) and triethylamine (82 ml) in acetonitrile (900 ml) was heated at reflux under a nitrogen atmosphere for a period of 16 hours. The reaction mixture was cooled to room temperature and the solvent removed in vacuo. Purification by flash column chromatography eluting with pentane:ethyl acetate (90:10 changing to 70:30 by volume) gave the title compound as an orange oil (54.3 g).
