4-Chloro-3-trifluoromethyl aniline was converted to the diazonium salt with sodium nitrite and sulfuric acid and this was reacted with acrylic acid (Meerwein reaction) to give 4-chloro-3-trifluoromethyl cinnamic acid. This acid was hydrogenated, reduced with lithium aluminum hydride to the alcohol and reacted with phosphorus tribromide to give 3(4-chloro-3-trifluoromethylphenyl)propyl bromide.
