| titleOfInvention | Process for the preparation of 4-amino-5-fluoro-3-chloro-6-(substituted) picolinates |
| abstract | 4‑Amino‑5‑fluoro‑3‑chloro‑6‑(substituted) picolinates consisting of trifluoroacetic acid, p-methoxyaniline, C 1 ‑C 4 alkyl propiolate and substituted methylene Base amines are prepared through a series of steps. Specifically, the present application provides the preparation of 4-amino-5-fluoro-3-chloro-6-(substituted) from non-pyridine sources without metal-assisted coupling and without the need for fluorination with expensive fluorinating agents The picolinate method. These picolinates are useful as herbicides. |
