3.5 G. of 2-amino-4-phenylthio-1-nitrobenzene in 8 ml. conc. hydrochloric acid is treated with a solution of 16 g. of stannous chloride in 8 ml. conc. hydrochloric acid. The mixture is heated for 1 hour on a steam bath, cooled and treated with potassium bicarbonate and chloroform. The mixture is filtered and the chloroform layer evaporated. The residue is triturated with hot cyclohexane yielding 1,2-diamino-4-phenylthiobenzene.
