New synthetic method for the bromination of 2, 6-dimethoxypyridine is proposed. The influence of alkali system, temperature, reaction time and reactant concentration on the bromination of 2,6-dimethoxypydine is systematically investigated. The results show that with the addition of organic base as HBr scavenger more starting material is released, and the yield of product is thus increased. The new method features in practicality, simplicity, and convenience in handling. The yield can reach as high as 75%, which is compatible with that produced under traditional conditions.
