60% Sodium hydride (38 mg) was suspended in dimethylimidazolinone (1 ml). 4-Phenylphenol (160 mg) was added while stirring under water-cooling, and the mixture was stirred under water-cooling for 0.5 hr. Methyl 4-bromo-6-quinolinecarboxylate (100 mg) was added under water-cooling and the mixture was stirred at 100° C. for 5 hr, and then at 140° C. for 3 hr. Water (10 ml) was added to the reaction mixture and the mixture was extracted once with ethyl acetate. The aqueous layer was made adjusted to pH 4 with 1N hydrochloric acid and the resulting solid was collected by filtration to give the object compound (73 mg) as a pale brown powder.
