Procedure

Employing standard chemical reactions, the 2,4-diaminothiophenol was prepared by first reacting sodium hydrosulfide with 2,4-dinitrochlorobenzene to produce 2,4-dinitrophenylmercaptan. The 2,4-dinitrophenylmercaptan was reduced with zinc and hydrochloric acid to produce 2,4-diamino-thiophenol.
