Reaction Steps

3-(2-Bromocyclopent-1-enyl)-benzoic acid ethyl ester (148 mg, 0.5 mmol), tetrakis(triphenylphosphine)palladium (0) (30 mg), potassium carbonate (0.20 g) and (2-benzyloxy-5-chlorophenyl) boronic acid (150 mg, 0.5 mmol) in dimethoxyethane (5 mL) were refluxed for 17 h under nitrogen. The reaction mixture was then filtered through Kieselguhr and evaporated down to an oil. Purification was carried out on a Water's separation pack (10 g) with dichloromethane/iso-hexane to give the product (85 mg).
