Procedure

5.7 G. of 1-acetamido-4-methylthiomethoxy-2-nitrobenzene is added to a mixture of 12 ml. 5N NaOH and 60 ml. methanol and the mixture heated for 15 minutes on a steam bath. The mixture is poured into 500 ml. water and is extracted with methylene chloride. The methylene chloride layer is separated, dried over sodium sulfate, and evaporated leaving 1-amino-4-methylthiomethoxy-2-nitrobenzene as a gum. This gum is dissolved in a mixture of 5 ml. acetic acid and 95 ml. methanol. 8 G. of iron powder is added and the mixture is heated at reflux for two hours. The methanol and acetic acid are evaporated and the residue is extracted with 200 ml. hot tetrahydrofuran. This solution is filtered and the tetrahydrofuran evaporated to yield 1,2-diamino-4-methylthiomethoxybenzene as a gum. This is purified by column chromatography.
