New downstream synthetic route of 5-Bromo-6-methoxypicolinic acid

At the same time, in my other blogs, there are other synthetic methods of this type of compound,1214334-70-9, 5-Bromo-6-methoxypicolinic acid, and friends who are interested can also refer to it.

Application of 1214334-70-9, Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 1214334-70-9, name is 5-Bromo-6-methoxypicolinic acid. A new synthetic method of this compound is introduced below.

[0436] To a stirred solution of 5-bromo-6-methoxypicolinic acid (350 mg, 1 mmol) in CH2C12 (2 mL) under an argon atmosphere were added oxalyl chloride (347 mg, 2 mmol) and DMF (catalytic amount) at 0 C. The reaction mixture was stirred at room temperature for 2 h. After consumption of acid (by TLC), the volatiles were evaporated in vacuo to give 5- bromo-6-methoxypicolinoyl chloride.
