Reaction Conditions

Reaction Steps

1.0 mL of methanol and 0.5 mL of 2.0 mol/L aqueous sodium hydroxide were added to 1.0 mL of dioxane solution containing 20 mg of tert-butyl 4-phenyl-2-(4-(1H-pyrrol-1-yl)benzamido)benzoate at room temperature and stirred at 50° C. for 30 minutes. Ethyl acetate and 1.0 mol/L hydrochloric acid were added after the reaction mixture was cooled to room temperature. The organic layer was separated and dried over anhydrous magnesium sulfate after washed with a saturated sodium chloride aqueous solution, and the solvent was evaporated under reduced pressure, Diisopropyl ether were added to toe obtained residue and a solid substance was separated by filtration to obtain 15 mg of 4-phenyl-2-(4-(1H-pyrrol-1-yl)benzamido)benzoic acid as white solid.
