Versuchsvorschrift

The compound of Structure (I-C) was prepared as follows. 2-carboxyanthraquinone was reacted with oxalyl chloride in dichloromethane (catalyzed by dimethylformamide) to yield 2-chlorocarbonylanthraquinone, which was then reacted with 1-hexanol in tetrahydrofuran (in the presence of triethylamine) to yield 2-n-hexoxycarbonylanthraquinone, which was then treated in a manner similar to Preparation A to prepare the Structure (I-C) compound with a yield of 50%. Structure was confirmed by IR and NMR spectroscopy.
