Reaction Steps
In a typical reaction, N-(5,5-diethoxy-1,1,1-trifluoropent-3-yn-2-ylidene)-1,1,1-triphenylmethanamine is mixed with about a 2.5 to 3 fold excess of (4-chloro-2-fluoro-3-methoxyphenyl)methyl 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 2-(4-chloro-2-fluoro-3-methoxyphenyl)-6-(diethoxymethyl)-3-fluoro-N-tritylpyridin-4-amine.
