Versuchsvorschrift

A mixture of 1-chloroanthraquinone (4 gm) potassium carbonate, (4 gm) in tetraethyleneglycol (15 ml) was heated for three hours at 120° C., poured into cool water and filtered off. The solid obtained was chromatographed over silica gel and eluted with methylene chloride:methanol (99:1) gave 1-[2-[2-[2-(2-hydroxyethoxy)ethoxy]ethoxy]ethoxy]-9,10-anthraquinone. This compound was crystallized from ether to give a yellow crystalline compound.
