METHOD OF OBTAINING 4-AMINO-5-FLUORO-3-HALOGEN-6-(SUBSTITUTED)PICOLINATES Russian patent published in 2015 - IPC C07D213/04 A01N43/40 A01P13/02

Abstract RU 2542985 C1

FIELD: chemistry.

SUBSTANCE: invention relates to method of obtaining 4-amino-5-fluoro-3-halogen-6-(substituted)picolinate of formula I , where W represents Cl, Br or I; R represents C₁-C₄ alkyl, cyclopropyl, C₂-C₄ alkenyl or phenyl, containing from 1 to 4 substituents, independently selected from halogen, C₁-C₄ alkyl, , C₁-C₄ halogenalkyl, C₁-C₄ alkoxy or C₁-C₄ halogenalkoxy; and R¹ represents C₁-C₁₂ alkyl or non-substituted or substituted C₇-C₁₁ arylalkyl; which includes the following stages: fluorine atom substitution, amination, halogen substitution, halogenations, hydrolysis of nitrile group, etherification and combination in presence of transition metal.

EFFECT: method improvement.
