Reaction Steps

To a mixture of 4-hydroxy-3-nitrobenzonitrile (4 g, 0.0244 mol) in ethanol (180 mL) and water (90 mL) was added sodium thiosulfate (17 g, 0.0976 mol) at room temperature. The heterogeneous mixture was stirred at 80° C. under an atmosphere of nitrogen for 1 hour. The reaction mixture was cooled to room temperature, and ethanol was removed under reduced pressure. The yellow solid was filtered, washed with water, and dried under reduced pressure to yield 3-amino-4-hydroxybenzonitrile (1.46 g, 0.011 mol).
