Participants

Reaction Steps

To a solution of 99 mg (2.53×10−4 mol) of 1-(3,4-dimethoxy-1-naphthyl)-8-(4-aminophenyl)-octane 537 and 35 mL (2.51×10−4 mol) of Et3N in 4 mL of MeOH were added 54 mg (2.53×10−4 mol) of 9-chloroacridine. The reaction mixture was stirred at room temperature for 20 hr. Evaporation of solvent and column chromatography on silica gel with first 1% MeOH in CH2Cl2 and then 3% MeOH in CH2Cl2 afforded 118.2 mg (82%) of acridine 538: 1H NMR (250 MHz, CDCl3, TMS) δ 8.14 (d, J=8 Hz, 1H), 8.0-7.9 (m, 5H), 7.66 (br t, 2H), 7.46 (t, J=8 Hz, 1H), 7.37 (t, J=8 Hz, 1H), 7.3-7.2 (m, 2H), 7.12 (s, 1H), 7.06 (d, J=8.4 Hz, 2H), 6.82 (d, J=8.4 Hz, 2H), 3.1-3.0 (m, 2H), 2.6-2.5 (m, 2H), 1.8-1.3 (m, 12H).
