, (2008/06/13)
Substituted aminoanthraquinone compounds, which are used for dye stuffs or intermediate thereof, represented by the formula (II) STR1 wherein R3 represents a C1 -C6 alkyl group which may be substituted, X represents a hydrogen atom, --COR1 or --SO2 R2 wherein R1 and R2 each represents a substituted or unsubstituted C1 -C4 alkyl or C6 -C12 aryl group, and Y and Z represent independently a hydrogen atom, a halogen atom, a nitro group or a C1 -C4 alkyl group, is prepared by allowing anthraquinone compounds represented by the formula STR2 wherein X, Y and Z are as defined above, to react with alkylating agents in organic solvents in the presence of organic quaternary ammonium salts and alkalies.
