Reaction Steps

A solution of benzyl 2-(4-bromophenyl)acetate (33.5 g. 0.11 mol), t-butyl acrylate (31.6 mL, 0.22 mol) and triethylamine (85 mL. 0.64 mol) in DMF (1000 mL) was deoxygenated with argon, whereupon bis(triphenylphosphine)palladium dichloride (5.1 g. 8.3 mmol) was added. After heating at 75° C. for 12 hours the solvent was removed in vacuo providing a brown residue that was purified by chromatography on silica gel using a mixture of hexanes and ethyl acetate (9:1) to give benzyl (E)-2-[4-[3-(1,1-dimethylethoxy)-3-oxo-1-propenyl]phenyl]acetate as a pale yellow oil (23.3 g. 0.07 mol) in 60% yield.
