Molecular formula:C17H14BrNO
Molecular Weight:328.2

3-benzyl-6-bromo-2-methoxyquinoline is a quinoline derivative, which can be used as an intermediate of bedaquiline, a potential drug for the treatment of tuberculosis. 3-Benzyl-6-bromo-2-chloroquinoline and sodium methoxide in dry methanol were refluxed for 8h. The reaction solution was purified to obtain 3-benzyl-6-bromo-2-methoxyquinoline.
