실험 절차

In a typical reaction, N-(5,5-diethoxy-1,1,1-trifluoro-pent-3-yn-2-ylidene)-4-methoxyaniline is mixed with about a 2.5 to 3 fold excess of p-chlorobenzylamine and about a 2.5 to 3 fold excess of cesium carbonate in anhydrous tetrahydrofuran. 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 2-(4-chlorophenyl)-6-(diethoxymethyl)-3-fluoro-N-(4-methoxyphenyl)pyridin-4-amine.
