Participants

Reaction Steps

A mixture of 5.52 g (0.02 mol) of 1,8-dichloroanthraquinone and 23.2 g (0.2M) 2-(diethylamino)ethylamine is heated under reflux for 3 hours. The reaction product is washed up as described in Example 1 except that the oily residue is only washed with water and then dried to yield 3.63 g of the title compound as the free base in the form of a purple solid, m.p. 103.5°-106.5° C.; λmax (deionised water) (E/cm/M) 236 nm (54940), 542 nm (13200).
