Reaction Steps

To a solution of 5-bromo-2-methyl-benzoic acid (1 g, 5.12 mmol, 1.0 eq) and (3-fluorophenyl)boronic acid (720 mg, 4.65 mmol, 1.1 eq) in a mixture of EtOH (5 mL), DMF (20 mL) and H2O (5 mL) were added Na2CO3 (1.98 g, 18.68 mmol, 4 eq) and Pd(PPh3)4 (270 mg, 0.23 mmol, 0.05 eq). The mixture was heated at 100° C. under N2 for 4 h and the reaction quenched by addition of 1M HCl. The aqueous phase was extracted with EtOAc and the combined organic extracts washed with brine, dried (Na2SO4), filtered and evaporated in vacuo. The residue was purified by chromatography (petroleum ether:EtOAc, 20:1 to 1:1) to give the title compound as a white solid (780 mg, 68%).
