To [1-(2-aminoethyl)-pyrrolidin-2-yl-]methanol (1.63 g, 11.3 mmol) in pyridine (10 mL) was added 1-chloroanthraquinone (1.37 g, 5.646 mmol), and the mixture was stirred at 65° C. for 24 hours. Pyridine was removed in vacuo and the resulting mixture of oil and solid was dissolved in CH2Cl2 and washed with H2O (3×50 mL) to remove any unreacted amine. The separated organic layer was removed in vacuo and the crude product was chromatographed using CH2Cl2/CH3OH (97:3). The desired product was yielded as a red powder (0.21 g, 11%).
