Potassium Carbonate → 1-(n-Octylsulfonylamino)-8-aminoanthraquinone

Participants

Reaction Steps

1-(n-octylsulfonylamino)-8-aminoanthraquinone was prepared as follows. 1-amino-8-chloroanthraquinone (1.0g), n-octanesulfonamide (1.0g), potassium carbonate (1.0g), cupric acetate monohydrate (0.85g) and chlorobenzene (16.0g) were refluxed for 5.5 hours. The cooled mixture was filtered and aqueous methanol was added to the filtrate. The supernatant liquid was decanted and the remaining oil was dissolved in dichloromethane. On addition of methanol and partial evaporation of the solvent, the product separated as a red solid.
