実験手順
A mixture of ethyl-2-[(3-bromo-2-methoxyphenyl)hydrazono]-3-oxobutanoate (4 g) prepared as in Example 1, 3-carboxyphenylboronic acid (2.30 g), bis(triphenylphosphine)palladium(II)chloride [PdCl2(PPh3)2] (0.30 g), potassium carbonate (4.023 g) in ethanol (100 mL) and water (30 mL) was heated to about reflux temperature and stirred for about 20 hours. The hot mixture was filtered to remove the catalyst. The clear filtrate was concentrated under vacuum. To the residue, water (100 mL) was added, acidified to pH 3-5 using hydrochloric acid and stirred for about 30 minutes at about room temperature. The slurry was filtered, washed with water (25 ml) and dried in an oven at about 55° C. to about 60° C. for about 12 hours.
