Reaction Steps

Trifluoroacetic acid 10 mL solution of the obtained tert-butyl 2-(4-fluoroanilino)-4-((E)-2-(3-methoxyphenyl)vinyl)benzoate was stirred at room temperature for 1 hour. The solvent was removed under reduced pressure, and ethyl acetate and saturated sodium thiosulfate aqueous solution were added to the obtained residue. The organic layer was separated and collected,dried over anhydrous magnesium sulfate after washing with saturated sodium chloride aqueous solution, and the solvent was removed under reduced pressure to give 2-(4-fluoroanilino)-4-((E)-2-(3-methoxyphenyl)vinyl)benzoic acid 28 mg of pale yellow solid.
