• Application and synthesis method

  3-Bromoquinoline can have action with mixed acid to generate 3-bromo-5-nitroquinoline, followed by heating with potassium permanganate to be oxidized to 5-bromo-2, 3-pyridine dicarboxylic acid.
  6-bromo-quinoline can be heated together nitric acid to generate 6-bromo-8-nitro-quinoline, followed by reaction with potassium permanganate to be oxidized into 2, 3-pyridinedicarboxylic acid.
  2-bromo-quinoline can be manufactured through the reaction between 2-hydroxyquinoline and phosphorus pentabromide
  3-bromo-quinoline can be obtained through heating the quinoline perbromide at 180 ° C.
  4-bromoquinoline can be obtained through either the heating reaction between 4-hydroxyquinoline and phosphorus pentabromide or by the diazotization reaction of 4-aminoquinoline.
  5-bromo-quinoline can be obtained from the heating reaction between m-bromo aniline, glycerol, m-bromonitrobenzene and concentrated sulfuric acid, or through the diazotization reaction of 5-amino-quinoline.
  6-bromo-quinoline can be obtained through the heating reaction between p-bromoaniline, glycerol, concentrated sulfuric acid and p-bromo-nitrobenzene.
  7-bromoquinoline can be obtained through the diazotization of 7-aminoquinoline.
  8-bromo-quinoline can be obtained through the heating of o-bromo aniline, glycerol, concentrated sulfuric acid and o-bromo-nitrobenzene in the heating system.
