A new synthetic route of 3-Amino-5-chloropicolinic acid

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,53636-68-3, its application will become more common.

Synthetic Route of 53636-68-3, 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. 53636-68-3, name is 3-Amino-5-chloropicolinic acid. A new synthetic method of this compound is introduced below.

3-Amino-5-chloropyridine-2-carboxylic acid (Int 2, 2 g, 11.6 mmol) was dissolved in NMP (100 mL) together with 1-amino-2-methyl-propan-2-ol (CAS: 2854-16-2, 1.14 g, 12.8 mmol), triethylamine (3.56 mL, 25.6 mmol) and HATU (4.87 g, 12.8 mmol). The resulting mixture was stirred at room temperature overnight. Next, the mixture was diluted with water and extracted with EtOAc. The organic fractions were combined, concentrated and the resulting crude residue was purified by column chromatography (petroleum ether/EtOAc 95/5 to 50/50) to give 3-amino-5-chloro-pyridine-2-carboxylic acid (2-hydroxy-2-methyl-propyl)-amide.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,53636-68-3, its application will become more common.
