Procedure
To a suspension of N,N-bis(2-chloroethyl)benzene-1,4-diamine hydrochloride (37) (0.918 g, 3 mmol) and charcoal (20 mg) in dry dioxane (30 mL) was added diphosgene (0.494 g, 2.5 mmol). The reaction mixture was heated at 90-95° C. for 5 h. After cooling, the reaction mixture was filtered through a pad of Celite and the filtrate containing crude mustard isocyanate 39 was added dropwise into the solution of 9-(5-amino-2-methyl-phenylamino)-5-methylacridine-4-carboxylic acid (2-dimethylaminoethyl)amide (0.732 g, 1.7 mmol)33 in dry DMF (25 mL) containing pyridine (2 mL) at −10° C. and then stirred at room temperature for 24 h. The solvent removed under reduced pressure to dryness and the residue was dissolved in a mixture of CHCl3/MeOH containing silica gel (10 gm) and evaporated in vacuo to dryness. The residue was put on the top of a silica gel column (4×30 cm) and chromatographed using CHCl3/MeOH (100:5 v/v) as eluent. The fractions containing the main product were combined and evaporated in vacuo to dryness. The residue was recrystallized from EtOH/hexane to give 9-[5-(3-{4-[bis(2-chloroethyl)amino]phenyl}ureido)-2-methyl-phenylamino]-5-methyl-acridine-4-carboxylic acid (2-dimethylaminoethyl)amide (19, BO-1053); 0.385 g (32%); mp 286-289° C.; 1H NMR (DMSO-d6) δ 2.19 (3H, s, Me), 2.67 (6H, m, NMe2), 2.85 (3H, s, Me), 3.14 (2H, brs, CH2), 3.63-3.69 (8H, m, 4×CH2), 3.85 (2H, brs, CH2), 6.41 (1H, m, ArH,), 6.65 (2H, d, J=9.0 Hz, ArH), 6.97 (1H, m, ArH), 7.24 (2H, d, J=9.0 Hz, ArH), 7.36-7.44 (1H, m, ArH), 7.51 (1H, m, ArH), 7.74 (2H, m, ArH), 7.93 (1H, m, ArH), 8.09 (1H, m, ArH), 8.41 (1H, m, ArH), 8.67 (1H, m, ArH), 9.04 (1H, brs, exchangeable, NH), 9.45 (1H, brs, exchangeable, NH), 12.18 (1H, brs, exchangeable, NH). Anal. Calcld. for (C37H41Cl2N7O2.6H2O): C, 54.91; H, 5.20; N, 12.34. Found: C, 55.08; H, 5.32; N, 12.44.
