-
, (2021/03/21)
The invention relates to a preparation method of a halogen-substituted pyridylamine compound, particularly to a preparation method of 4-amino-2,6-dichloropyridine, wherein 2,6-dihydroxy isonicotinic acid is used as a raw material and is subjected to chlorination reaction, Curtius rearrangement or further amine protection group removal to obtain the product. The method has the advantages of accessible raw materials, high yield and low impurity content, avoids the use of explosive reagent sodium azide, and can be further applied to industrial production.
