Reaction Steps

To a solution of methyl 4-methoxy-6-quinolinecarboxylate (910 mg) in DMF (7 ml) was added phosphorus tribromide (1.57 ml) while stirring under ice-cooling. DMF (7 ml) was added and the mixture was heated at 80° C. for 3 hr. To the reaction mixture was added water (50 ml) and the reaction mixture was made weak basic with a 1N aqueous sodium hydroxide solution. The resulting precipitate was collected by filtration and purified by silica gel column chromatography (eluent: chloroform-methanol=100/0-100/1) to give the object compound (420 mg) as a yellow powder.
