Hydrazine (0.83 mL, 26.4 mmol) is added dropwise to a solution of 4-chlorophenyl isocyanate (3.85 g, 25.1 mmol) in 1,2-dichloroethane. The reaction mixture is stirred overnight at room temperature and filtered. The filter cake is washed with ether and dried to give the title product as a white solid, 4.28 g, which is identified by 1HNMR spectral analysis.
