2 ml of trifluoroacetic acid were added to a solution of (E)-3-(4-{(E)-3-[4-(1-methyl-piperidin-4-yl)-phenyl]-3-oxo-propenyl}-phenyl)-acrylic acid tert-butyl ester (270 mg, 0.63 mmol) in 10 ml of DCM. The solution was stirred at room temperature for 2 hours. The solvent was then removed until dryness and 300 mg of (E)-3-(4-{(E)-3-[4-(1-methyl-piperidin-4-yl)-phenyl]-3-oxo-propenyl}-phenyl)-acrylic acid trifluoro acetate were obtained as a yellow solid.
