Reaction Steps
3-{4-[3-(3,4-difluoro-phenyl)-3-oxo-propenyl]-phenyl}-acrylic acid tert-butyl ester (210 mg, 0.56 mmol) was dissolved in DCM (5 ml) and trifluoroacetic acid was added (2 ml). The reaction was stirred at room temperature for 12 h. The solvent was evaporated under vacuo giving 200 mg of 3-{4-[3-(3,4-difluoro-phenyl)-3-oxo-propenyl]-phenyl}-acrylic acid.
