A solution of 3-chloro-2-(2,4-dichlorophenylthio)-nitrobenzene (10.04 g) in dioxan (100 ml) is mixed with Raney-nickel (5 g). Following this, the mixture is shaken for 3 hours at room temperature and 3 bar hydrogen pressure in a Parr apparatus. The catalyst is removed by filtration. The filtrate is concentrated in a vacuum and the resulting residue is brought to constant weight in a vacuum. Yield 9.01 g (98.6%) of colourless oil.
