Synthesis

1609453-56-6

1609452-31-4

7,8-Dibromo-2-chloro-9-methyl-5,6-dihydro-4H-imidazo[4,5,1-IJ]quinoline was synthesized as follows (Method 2A): 2-chloro-9-methyl-5,6-dihydro-4H-imidazo[4,5,1-IJ]quinoline (11.7 g, 56 mmol, Method 14A) was dissolved in acetonitrile (250 mL) pre-cooled to 0 °C in acetonitrile (250 mL). Subsequently, N-bromosuccinimide (50.0 g, 282 mmol) was added in batches over 1 hour. The reaction mixture was continued to be stirred at 0 °C for 30 min, after which it was brought to room temperature and stirred for 48 hours. After completion of the reaction, the solvent was removed by distillation under reduced pressure. The residue was dissolved in dichloromethane and washed with saturated aqueous sodium bicarbonate. The organic layer was dried over anhydrous sodium sulfate, filtered and concentrated the filtrate to afford 18.6 g of the target product 7,8-dibromo-2-chloro-9-methyl-5,6-dihydro-4H-imidazo[4,5,1-IJ]quinoline in 90% yield. The product was characterized by LC-MS (m/z 364.8 [M + 1]) and 1H NMR (600 MHz, DMSO) δ 4.12 (t, 2H, CH2), 2.88 (t, 2H, CH2), 2.57 (s, 3H, CH3), 2.22-2.18 (m, 2H, CH2).
