실험 절차

Another embodiment of the present disclosure includes a method of producing methyl 4-amino-3-chloro-6-(4-chloro-2-fluoro-3-methoxyphenyl)pyridine-2-carboxylate. The method comprises producing an aqueous solution comprising 4-chloro-2-fluoro-3-methoxyphenylboronic acid. Methyl isobutyl ketone is added to the aqueous solution. The methyl isobutyl ketone and 4-chloro-2-fluoro-3-methoxyphenylboronic acid are separated from the water. The 4-chloro-2-fluoro-3-methoxyphenylboronic acid is reacted with methyl 4-(acetylamino)-3,6-dichloropyridine-2-carboxylate in methyl isobutyl ketone to produce methyl 4-(acetylamino)-3-chloro-6-(4-chloro-2-fluoro-3-methoxyphenyl)pyridine-2-carboxylate, which is deacetylated to produce methyl 4-amino-3-chloro-6-(4-chloro-2-fluoro-3-methoxyphenyl)pyridine-2-carboxylate.
