| titleOfInvention | Process for preparing 2-amino-5-methyl-6-halogenated pyridine |
| abstract | The invention relates to a method for preparing 2-amino-5-methyl-6-halogenated pyridine, which takes 2-halogen-3-methylpyridine nitrogen oxide as a raw material, and reacts in a reaction solvent to obtain 2-amino-5-methyl-6-halogenated pyridine under the action of acid anhydride, an acid-binding agent and an amination reagent, wherein the reaction solvent is halogenated alkane, the 2-amino-5-methyl-6-halogenated pyridine/4-position isomer of the product of the method can reach 93/7, the product purity is up to more than 99.8 percent, the reaction yield is more than 70 percent, and the method has strong scalability and good process stability and can realize large-scale industrial production. |
