Reaction Steps

The product from Example 15B (165 mg, 0.3 mmol), 5-fluoro-2-methoxyphenylboronic acid (68 mg, 0.4 mmol) and tetrakis(triphenylphosphine)palladium(0) (17 mg, 0.015 mmol) in THF (10 ml) were treated with 3M aqueous sodium carbonate (0.4 mL) and heated at reflux for 16 hours. After cooling to room temperature, the reaction mixture was diluted with water, acidified with 1N hydrochloric acid and extracted with diethyl ether. The organic layers were combined, dried with magnesium sulfate, filtered and the filtrate concentrated. The residue was purified by a Prep Nova Pak (HRC18) column using 0.1% trifluoroacetic acid:acetonitrile (10:90 to 95:5) as eluant to provide the title compound (50 mg).
