The reaction crude was allowed to cool to room temperature, and an aqueous solution of sodium carbonate was added until pH 8. The crude material was extracted with dichloromethane (3×50 mL), magnesium sulfate was added to the organic phase, filtered and the solvent was removed under reduced pressure, thus affording 2.374 g (11.143 mmol, yield=100%) of 3-aminophenyl benzoate.
