Acetic Anhydride → N-[2-Nitro-5-(phenylsulfanyl)phenyl]acetamide

Participants

Reaction Steps

6.0 G. of 2-amino-4-phenylthio-1-nitrobenzene is dissolved in 80 ml. acetic anhydride and treated with a few drops of sulfuric acid. The mixture is left at 20°-30° C for 2 hours then a little sodium acetate added and the solvent removed under vacuum. The residue is treated with water, filtered and recrystallized from methanol yielding 2-acetamido-4-phenylthio-1-nitrobenzene. This material may also be obtained by reaction of 2-acetamido-4-chloro-1-nitrobenzene with sodium phenylmercaptide essentially as described above for the free amine.
