Procedure

Tributyl(1-ethoxyvinyl)tin (1.07 mmol, 3.18 mmol) and dichlorobis(triphenylphosphine)palladium(II) (101 mg, 0.145 mmol) were added to a solution of N-(4-bromo-3-methylphenyl)-N-methylacetamide (700 mg, 2.89 mmol) in 1,4-dioxane (7 mL), and the mixture was heated with stirring at 90° C. for 12 hours in a nitrogen stream. The reaction mixture was cooled and then filtered through celite. The solution was concentrated under reduced pressure, and the residue was then silica gel column chromatography (hexane-ethyl acetate) to give N-[4-(1-ethoxy-vinyl)-3-methyl-phenyl]-N-methyl-acetamide (440 mg, 65%).
