Reaction Conditions

Reaction Steps

A mixture containing 11.85 g (0.035 mol) of methyl 2-[4-(5-trifluoromethyl-2-pyridyloxy)phenoxy]-propionate and 11.5 g (0.2 mol) of allylamine is boiled under reflux (about 60° C.) for 10 hours. (The reaction is followed by gas chromatography.) Thereafter, the excess of allylamine is distilled off and the residue is dissolved in benzene. After washing the solution cooled down with 5% aqueous hydrochloric acid and then with saturated sodium chloride solution, the organic phase is dried over anhydrous magnesium sulfate and evaporated. The crude product is recrystallized from petroleum ether (b.p. 120° C.) containing a small amount of toluene.
