General description

2-Bromo-4-methylanisole can be prepared via bromination of 4-methylanisole using poly(4-vinylpyridinium bromochromate).

Application

2-Bromo-4-methylanisole may be used in the synthesis of:
  • 1,6-bis(2-hydroxy-5-methylphenyl)pyridine (H2mdppy)
  • 1,8-dimethoxy-4-methylanthra-quinone
  • ethyl 2-(2-methoxy-5-methylphenyl)-2-methyl-4-oxocyclopentanecarboxylate
It may be used as starting material in the multi-step synthesis of sesquiterpene (±)-herbertenolide.
