反応手順
19 g of triphenylphosphine dibromide were added to a solution of 5.39 g of 3-chloro-4-hydroxy-6,7-dimethoxyquinoline in 270 cm3 of acetonitrile, with stirring and at a temperature in the region of 20° C. The reaction mixture was heated at about 80° C. for 8.25 hours. After cooling to a temperature in the region of 20° C., the insoluble material was filtered off. 5.67 g of 4-bromo-3-chloro-6,7-dimethoxyquinoline were obtained in the form of a gray solid.
