PROCEDURE

实验过程

In a typical reaction, methyl 5,5,5-trifluoro-4-((4-methoxyphenyl)imino)pent-2-ynoate is mixed with about a 2.5 to 3 fold excess of 4-chlorobenzyl amine and about a 2.5 to 3 fold excess of cesium carbonate in anhydrous terahydrofuran. The mixture is heated at about 80° C. until the reaction is complete. After cooling, an extraction solvent like a halogenated hydrocarbon is added to the mixture along with water. The organic layer is recovered, washed with brine and dried. The solvent is evaporated to provide crude methyl 4-(4-methoxyphenylamino)-5-fluoro-6-(4-chlorophenyl)picolinate.
