Procedure

A mixture of 4-[4-(2-chloro-4-trifluoromethylphenoxy) phenoxy]-3-methoxy-2-pentenoyl chloride (15 mm) and THF (15 ml.), at 0°, is prepared and then slight excess of methylamine introduced. The reaction mixture is allowed to stand under nitrogen for about one hour. Then the reaction is allowed to rise to RT and solvent removed. The residue is taken up in methylene dichloride, washed, dried and solvent removed under vacuum to yield N-methyl 4-[4-(2-chloro-4-trifluoromethylphenoxy) phenoxy]-3-methoxy-2-pentenamide.
