Reaction Conditions

Reaction Steps

A mixture of 15 g (44.6 mmol) of 9,10-dibromoanthracene, 7.7 g (44.6 mmol) of naphthalen-2-ylboronic acid, 0.52 g (0.446 mmol) of Tetrakis(triphenylphosphine)Palladium, 33 ml of 2M Na2CO3, 60 ml of EtOH and 150 ml toluene was degassed and placed under nitrogen, and then heated at 90° C. for 24 h. After the reaction finish, the mixture was allowed to cool to room temperature. The organic layer was extracted with ethyl acetate and water, dried with anhydrous magnesium sulfate, the solvent was removed and the residue was purified by column chromatography on silica (hexane-dichloromethane) to give product 10.4 g (61%) as a yellow solid.
