Palladium(II) acetate (0.056 g), tri-o-tolylphosphine (0.148 g), 2-bromonaphthalene (0.49 g) and triethylamine (10 ml) were added to a solution of (±)-5-(3-pyridyl)-1-penten-3-ol (0.40 g) in acetonitrile (30 ml) and the mixture heated at 100° C. for 24 hours. The solvents were removed under reduced pressure and water was added to the residue. The mixture was extracted with dichloromethane, the combined extracts dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure. The residue was purified by column chromatography over silica eluting with dichloromethane:ethyl acetate (2:1) to give the sub-title ketone as a brown oil (0.327 g).
