Reaction Steps

To dioxane 2.0 mL solution of tert-butyl 4-phenethyl-2-(3-(1H-pyrrol-1-yl)phenylamino)benzoate 83 mg were added methanol 2.0 mL and 2.0 mol/L sodium hydroxide aqueous solution 1.0 mL, and it was heated and refluxed for 3 hours. After the reaction mixture was cooled to room temperature, ethyl acetate and 1.0 mol/L hydrochloric acid were added to it. 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. Diisopropyl ether was added to the obtained residue, and solid matter was filtrated to give 4-phenethyl-2-(3-(1H-pyrrol-1-yl)phenylamino)benzoic acid 36 mg of a white solid.
