Procedure

To a solution of 9-methylacridine (1.93 g, 10 mmol) in dichloromethane (100 mL) was added NBS (1.78 g, 10 mmol) portion-wise in an ice-water bath. After complete addition, the solution mixture was warmed to room temperature and stirred overnight. The resulting solution was washed with water and brine. The organic phase was dried over anhydrous sodium sulfate and the solvent was removed. The residue was purified by silica gel chromatography using ethyl acetate and petroleum ether (EA:PE=1:5) as eluent to afford 10 (2.08 g) in 77% yield. 1H NMR (400 MHz, CDCl3) δ 8.27 (d, J=8.8 Hz, 4H), 7.81 (t, J=8.0 Hz, 2H), 7.68 (t, J=8.0 Hz, 2H), 5.42 (s, 2H). 13C NMR (400 MHz, CDCl3) δ 148.9, 138.7, 130.5, 130.1, 126.8, 123.8, 123.4, 23.1. MS (FAB) m/z Calcd for C14H10BrN 272.1. Found 2722. [M]+.
