- 摘要：
- Methods of producing methyl 4 amino 3 chloro 6 (4 chloro 2 fluoro 3 methoxyphenyl)pyridine 2 carboxylate. One method comprises adding methyl isobutyl ketone to an aqueous solution comprising 4 chloro 2 fluoro 3 methoxyphenyl boronic acid to form an organic phase comprising the 4 chloro 2 fluoro 3 methoxyphenylboronic acid and an aqueous phase. The organic phase and the aqueous phase are separated. 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.
