2-Chloro-4-nitrobenzene-1-thiol → 4-Amino-2-chlorobenzenethiol

Participants

Reaction Steps

To 2-chloro-4-nitrobenzenethiol (4.0 g) was added acetic acid (60 ml), and to this solution was added reduced iron (21 g), and the mixture was stirred at room temperature for 3 hours. The mixture was filtered with Celite, and washed with ethyl acetate. The solvent was removed under reduced pressure, and the obtained residue was purified by silica gel column chromatography, to give 4-amino-2-chlorobenzenethiol (2.74 g).
