To a 2 dram vial charged with 2-fluoro-5-methoxyphenylboronic acid (available from Aldrich) (3.17 g, 18.7 mmol), tetrakis(triphenylphosphine)palladium (0) (0.719 g, 0.622 mmol), cesium fluoride (1.15 mL, 31.1 mmol), and 26.2 (1.96 g, 6.22 mmol), was added DME (20 mL). The reaction mixture was then heated at 90° C. overnight. The reaction was allowed to cool and then filtered and concentrated. The crude product was purified by combiflash (0 to 10% EtOAc/hexanes) yielding 26.3 (1.61 g, 71.8% yield).
