Procedure

Into a 250 ml round-bottom flask equipped with magnetic stirrer, condenser, heating mantle and nitrogen blanket, were placed 10.0 g of 1-aminoanthraquinone, 80 ml of nitrobenzene and 6.5 g of n-heptanoyl chloride. The solution was refluxed for 2.5 hours and cooled. Crude product was precipitated with methanol, filtered and dried. Chromatography on silica gel with toluene eluent afforded yellow 1-n-heptanoylaminoanthraquinone, melting at 133° C.
