الإجراء التجريبي

Allylbenzene (255 μL, 1.9 mmol), 4-bromobenzoic acid (523 mg, 2.6 mmol), Et3N (0.91 mL, 6.5 mmol), Palladium (II) Acetate (16 mg, 0.052 mmol), triphenylphosphine (60 mg, 0.21 mmol) and acetonitrile (5 mL) were stirred at reflux overnight in a round bottom flask. Added HCl 1N, extracted with EtOAc, dried the organic layer on anhydrous MgSO4, filtered, evaporated solvent under vacuum. Purified by column chromatography using 10% MeOH/CH2Cl2 yielded 90 mg (14%) of mixture of two regioisomers 54. The mixture was then submitted for hydrogenation without further characterization.
