실험 절차

To a stirred solution of 4-iodo-5-chloro-2-methoxy benzoic acid of Example 20, Step A (3.72 g, 19.1 mmol) in N,N-dimethylformamide (20 mL) was added 2-fluorophenyl boronic acid (5.0 g, 35.7 mmol) and potassium carbonate (14.8 g, 107 mmol). This mixture was purged with nitrogen and then treated with a catalytic amount of tetrakis(triphenylphosphine) palladium(0) (0.688 g, 0.59 mmol). The reaction was heated to reflux overnight, cooled, acidified with 2 N hydrochloric acid and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous magnesium sulfate, filtered, and evaporated to dryness. The residue was flash chromatographed on acid washed silica using a 10 to 50% gradient of diethyl ether in hexane to provide the desired title compound (3.8 g) as a white solid.
