A mixture of 3-bromo-benzoic acid (4.02 g) and 4-ethoxycarbonyl-phenyl boronic acid (3.88 g) in DME (100 ml) containing cesium carbonate (6.5 g) and tetrakis(triphenylphosphine) palladium (0) (1.15 g) was heated to reflux for 24 h. The cooled mixture was then filtered through celite and evaporated giving the crude title compound as a white solid which was used without purification in the next synthetic step.
