How is 4-Bromo-2-methoxyaniline (CAS: 59557-91-4) typically synthesized?

4-Bromo-2-methoxyaniline (CAS: 59557-91-4) is typically synthesized via the bromination of 2-methoxyaniline. This process involves treating 2-methoxyaniline with bromine in the presence of a suitable base such as sodium hydroxide. The reaction is carried out in an aqueous phase, and the product can be isolated by extraction or recrystallization. The yield can be improved by optimizing the reaction conditions and using appropriate catalysts.
