Versuchsvorschrift

10% Sodium hydroxide aqueous solution 0.82 mL was added to a suspension of ethanol 3.0 mL of methyl 4-(benzylamino)-2-(4-fluoroanilino)benzoate 0.24 g at room temperature, and it was heated and refluxed for 2 hours. After the reaction mixture was cooled to room temperature, 10% sodium hydroxide aqueous solution 0.82 mL was added, and it was heated and refluxed for 3 hours. After the reaction mixture was cooled to room temperature, acetic acid 2.0 mL, saturated sodium chloride aqueous solution and ethyl acetate were added to it. The organic layer was separated and collected, dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure. Diisopropyl ether and hexane were added to the obtained residue, and solid matter was filtrated to give 4-(benzylamino)-2-(4-fluoroanilino)benzoic acid 0.17 g of white solid.
