3-Nitrophenyl benzoate (2.7080 g, 11.144 mmol) and tin (II) chloride dihydrate (12.564 g, 55.720 mmol) were dissolved in 60 mL of ethanol and heated at 100° C. for 1 hour. 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.
