Procedure

To the 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 in 1-(bromomethyl)-2-methylbenzene (0.525 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˜90% EtOAc in Hexane) to give the product as solid (0.726 g, 77%). 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 2.43 (s, 3H) 2.54 (s, 3H) 3.00-3.14 (m, 4H) 3.78-3.90 (m, 4H) 5.22 (s, 2H) 6.44 (d, J=7.83 Hz, 1H) 6.53 (d, J=2.02 Hz, 1H) 7.02-7.12 (m, 1H) 7.15 (d, J=2.02 Hz, 1H) 7.18-7.27 (m, 2H); MS (ES+) m/e 400.0 [M+H]+.
