実験手順
Methyl 5-bromo-8-methoxyquinoline-2-carboxylate (154 g), tetrahydrofuran (40 ml), water (40 ml) and lithium hydroxide monohydrate (0.436 g) were combined and stirred at room temperature for 1.5 h. The tetrahydrofuran was removed in vacuo and the resulting aqueous mixture was acidified with hydrochloric acid. The resulting white precipitate was collected by filtration and dried in vacuo to give the title compound (1.33 g) as a white solid.
