Reaction Steps
2M Aqueous sodium bicarbonate (10 mL) was added to a suspension of 2-bromo-3-methoxybenzoic acid ethyl ester (2.06 g, 7.7 mmol), benzeneboronic acid (1.11 g), and tetrakis(triphenylphosphine)palladium(0) (0.30 g) in toluene (35 mL) under a nitrogen atmosphere. The mixture was stirred at 80° C. for 2 hours, poured into water, and extracted with diethyl ether. The organic layer was evaporated, and the residue was chromatographed, eluting with hexane/acetone (3:1) to give a semisolid oil. Recrystallization from diethyl ether/hexane gave 3-methoxy-2-phenylbenzoic acid ethyl ester as colorless crystals (0.69 g, 34%).
