Phase transfer catalysed N-monoalkylation of amino anthraquinones

1-Alkylaminoanthraquinones (2a-f) and 1,4-bisalkylaminoanthraquinones (4a-c) were prepared from aminoanthraquinones (1,3) by alkylation with alkyl sulphate/alkyl halide in presence of powdered sodium hydroxide, potassium carbonate and phase transfer catalyst.
