9Substitution General Procedure [0633] To a vigorously stirred solution of BR-ACO-18 in CHCl3 was added dropwise a solution of the proposed amine, Q-NH2 (e.g., NH2(CH2)pNH2, substituted anilines), for example7 in CHCl3. This solution was stirred for a further 2 hr, the solvent was then removed under reduced pressure and the resultant solid washed with EtOH and Et2O to give the desired trisubstituted derivative. Example 55 N-{9-[4'-(N,N-Dimethylamino)phenylamino]}-3,6-bis(3-pyrrolidinopropionamido)acridine (BR-ACO-21) [0636] 3,6-Bisamido-9-chloroacridone BR-ACO-18 (400 mg, 0.8 mmol) was treated with 4-N,N-dimethylaminoaniline (0.5 mL) according to the general procedure to give the desired product BR-ACO-21 (400 mg, 88%) as a brown solid.
