Reaction Steps
0.24 mL of 2.0 mol/L aqueous sodium hydroxide was added to a mixed solution of 1.0 mL of dioxane and 1.0 mL of methanol containing 58 mg of tert-butyl 2-(benzamido)-4-(1H-pyrrol-1-yl)benzoate and stirred at 50° C. for 1 hour and 30 minutes. After the reaction mixture was cooled to room temperature, water was added and after pH was adjusted to pH 3.0 with 1.0 mol/L hydrochloric acid, ethyl acetate was added. The organic layer was separated and dried over anhydrous magnesium sulfate after washed with water and a saturated sodium chloride aqueous solution sequentially, and the solvent was evaporated under reduced pressure. Diisopropyl ether were added to the obtained residue and a solid substance was separated by filtration to obtain 41 mg of 2-(benzamido)-4-(1H-pyrrol-1-yl)benzoic acid as white solid.
