How is 5-Bromo-8-methoxy-2-methylquinoline (CAS: 103862-55-1) typically synthesized?

5-Bromo-8-methoxy-2-methylquinoline is typically synthesized through a multistep process involving alkylation of 8-hydroxy-2-methylquinoline followed by bromination. The synthesis often uses bromine in pyridine as a brominating agent, and the reaction is carried out under nitrogen to avoid oxidation. The overall yield is moderate, around 60-70%, with good selectivity towards the brominated product.
