To a solution of 2-(4-chloroanilino)-nitrobenzene (57.0 g) in CH2Cl2 (40 mL) was added AcOH (90 mL), then Zn powder (105 g) was added in small portions. After Zn powder was added, the color of the mixture became light green, filtered by suction, washed with CH2Cl2. The filtrate was concentrated to dryness. Water was added, filtered, and washed with water to give a brown solid. This solid was used directly in the next step without further purification.
