Potassium Carbonate → Benzoic acid, 3-[2-[2-(phenylmethoxy)phenyl]-1-cyclopenten-1-yl]-

Participants

Reaction Steps

3-(2-Bromo-cyclopent-1-enyl] benzoic acid ethyl ester (0.148 g, 0.0005 mol), tetrakis-triphenylphosphine palladium (o) (30 mg), potassium carbonate (0.200 g) and (2-benzyloxyphenyl) boronic acid (0.110 g, 0.5 mmol) in dimethoxyethane (5 mL) were refluxed for 17 h under nitrogen. The reaction mixture was then filtered through Keiselghur and evaporated down to an oil. Purification was carried out on a Waters separation pack (10 g) cartridge with dichloromethane/iso hexane giving the product (120 mg).
