A solution of ethyl 2-[4-(2-{(aminocarbonothioyl)[4-(trifluoromethyl)benzyl]amino}ethyl)phenoxy]-2-methylpropanoate (162 mg; 0.35 mmol) and 3-chlorophenacyl bromide (82 mg; 0.35 mmol) in EtOH (4 ml) was heated to reflux for 12 hr. Upon cooling the mixture was concentrated and the residue purified by flash chromatography using ethyl acetate-hexane mixtures (5–50% gradient) to afford ethyl 2-[4-(2-{[4-(3-chlorophenyl)-1,3-thiazol-2-yl][4-(trifluoromethyl)benzyl]amino}ethyl)phenoxy]-2-methylpropanoate (128 mg; 61% yield).
