Procedure
Trifluoroacetic acid 15 ml solution of the obtained tert-butyl 2-(4-fluoroanilino)-4-((E)-2-(pyridin-3-yl)vinyl)benzoate was stirred at room temperature for 2 hours. The solvent was removed under reduced pressure, ethyl acetate and water were added to it, and it was adjusted to pH6.0 with saturated sodium hydrogen carbonate aqueous solution. The organic layer was separated and collected,dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure to give 2-(4-fluoroanilino)-4-((E)-2-(pyridin-3-yl)vinyl)benzoic acid 46 mg of pale yellow solid.
