Procedure

To a mixture of 4-(4-bromo-2-methyl-1H-benzo[d]imidazol-6-yl)morpholine (0.7 g, 2.364 mmol) in N,N-Dimethylformamide (DMF) (10 mL) was added 1-(bromomethyl)-3-chlorobenzene (0.583 g, 2.84 mmol) and potassium carbonate (0.980 g, 7.09 mmol). The resulting reaction mixture was stirred at 90° C. for 4 h. It was cooled to room temperature and poured into water (100 mL). The aqueous mixture was extracted with DCM (100 mL×2). The combined organic phases were washed with Brine (100 mL) and concentrated. The crude material was purified on silica column (20˜70% EtOAc in Hexane) to give the product as solid (0.65 g, 65%). 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 2.57 (s, 3H) 2.90-3.16 (m, 4H) 3.69-3.95 (m, 4H) 5.25 (s, 2H) 6.60 (d, J=2.02 Hz, 1H) 6.88 (d, J=7.07 Hz, 1H) 7.07 (s, 1H) 7.16 (d, J=2.02 Hz, 1H) 7.20-7.37 (m, 2H); MS (ES+) m/e 420.0 [M+H]+.
