Procedure

Trifluoroacetic acid 15 mL solution of the obtained tert-butyl 4-((E)-3-cyclohexyl-1-propenyl)-2-(4-fluoroanilino)benzoate was stirred at room temperature for 2 hours. The solvent was removed under reduced pressure, and the obtained residue was refined by reversed-phase silica gel column chromatography [eluent; 70-100% acetonitrile/0.1% trifluoroacetic acid aqueous solution] to give 4-((E)-3-cyclohexyl-1-propenyl)-2-(4-fluoroanilino)benzoic acid 23 mg of pale yellow solid.
