To a solution of 636.9 mg (3.07 mmol) of 4-(7-hydroxyheptyl)-aniline 30 and 428 μL (3.07 mmol) of Et3N in 20 mL of MeOH were added 656.4 mg (3.07 mmol) of 9-chloroacridine. After stirring for 7 hr at room temperature, the solvent was evaporated. Purification by column chromatography on silica gel with 5% MeOH in CH2Cl2 gave 1.079 g (91%) of N-(9-acridinyl)-4-(7-hydroxyheptyl)-aniline 31: 1H NMR (300 MHz, CDCl3, TMS) δ 8.0-7.9 (m, 4H), 7.63 (t, J=7 Hz, 2H), 7.3-7.2 (m, 2H), 7.07 (d, J=8.3 Hz, 2H), 6.85 (d, J=8.3 Hz, 2H), 3.64 (t, J=6.6 Hz, 2H), 2.57 (t, J=7.6 Hz, 2H), 1.7-1.5 (m, 4H), 1.4-1.3 (m, 6H). N-(9-acridinyl)-4-(7-iodoheptyl)-aniline (32). To a solution of 604.1 mg (1.57 mmol) of N-(9-acridinyl)-4-(7-hydroxyheptyl)-aniline 31 in 20 mL of pyridine cooled to 0° C. was added 200 μL (2.58 mmol) of methanesulfonyl chloride. The reaction mixture was stirred at 0° C. for 1 hr 20 min, then partitioned between 180 mL of CH2Cl2 and 75 mL of water. The aqueous phase was extracted with CH2Cl2 (3×30 mL). The CH2Cl2 extracts were combined, washed with 40 mL of saturated NaCl solution, dried with MgSO4, and evaporated to dryness.
