N-Hexyl-N-[2-[4-(3,3-dimethoxy-4,4,4-trifluorobut-1-yl)phenoxy]ethyl]dodecylamine (353 mg, 0.63 mmol) was treated with trifluoroacetic acid as described in the preparation of 4-[N-dodecyl-N-[2-[4-(4,4,4-trifluoro-3-oxobut-1-yl)phenoxy]ethyl]amino]butanoic acid, ethyl ester . The residue was chromatographed on silica gel (dichloromethane/methanol 98:2 to 94:6) to afford the title compound (253 mg, 78%) as a pale yellow oil.
