Reaction Steps
1-Nitroanthraquinone is refluxed with an excess of cyclohexylamine in o-dichlorobenzene to yield 1-cyclohexylamino anthraquinone which is further brominated in aqueous pyridine to yield the corresponding 1-cyclohexylamino-4-bromoanthraquinone. This compound is further condensed with p-amino acetanilide to yield 1-cyclohexylamino-4-(p-acetaminoanilino)anthraquinone as a bright green pleochroic dye having an optical order parameter 0.7.
