To the mixture of 4-(4-bromo-2-methyl-1H-benzo[d]imidazol-6-yl)morpholine (0.4 g, 1.351 mmol) in N,N-Dimethylformamide (DMF) (10 mL) was added 1-(bromomethyl)-2,3-dimethylbenzene (0.323 g, 1.621 mmol) and potassium carbonate (0.560 g, 4.05 mmol). The resulting reaction mixture was stirred at 80° C. for 3 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 (0.4 g, 71%). 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 2.33 (s, 3H) 2.37 (s, 3H) 2.53 (s, 3H) 2.98-3.14 (m, 4H) 3.66-3.93 (m, 4H) 5.24 (s, 2H) 6.24 (d, J=7.58 Hz, 1H) 6.53 (d, J=2.27 Hz, 1H) 6.89-7.00 (m, 1H) 7.06-7.17 (m, 2H); MS (ES+) m/e 414.1 [M+H]+
