실험 절차
A mixture of 1,5-dichloroanthraquinone (5.5 g, 20 mmol) and N,N,N′-trimethylethylenediamine (40 ml) was refluxed for 18 h. The mixture was cooled to room temperature, diluted with water (400 mL) and extracted with chloroform (2×200 mL). The combined organic layer was washed with water, brine, dried over MgSO4 and evaporated to dryness. The residue thus obtained was purified by silica gel flash chromatography [CHCl3/MeOH/Et3N (44:5:1)] to provide Compound 9. Abs (max, PBS pH 7.4)=508 nm. The structure of Compound 9 is given below:
