How is (2,4-Dichlorophenyl)hydazine (CAS: 13123-92-7) typically synthesized?

(2,4-Dichlorophenyl)hydazine is commonly synthesized by the reduction of 2,4-dichlorophenylhydrazine hydrochloride with a suitable reducing agent such as sodium borohydride or lithium aluminum hydride. The reaction typically proceeds with high yield and good selectivity, though appropriate precautions must be taken due to the potential for explosive decomposition under certain conditions.
