To a mixture of 4-(4-bromo-2-methyl-1H-benzo[d]imidazol-6-yl)morpholine (0.5 g, 1.688 mmol), prepared as described in example 1, in N,N-Dimethylformamide (DMF) (10 mL) was added 1-(bromomethyl)naphthalene (0.448 g, 2.026 mmol) and potassium carbonate (0.700 g, 5.06 mmol). The resulting reaction mixture was stirred at 80° 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 (0.53 g, 72%). 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 2.57 (s, 3H) 2.97-3.13 (m, 4H) 3.61-3.89 (m, 4H) 5.76 (s, 2H) 6.53 (dd, J=7.07, 1.01 Hz, 1H) 6.56 (d, J=2.02 Hz, 1H) 7.17 (d, J=2.02 Hz, 1H) 7.32 (m, 1H) 7.58-7.73 (m, 2H) 7.83 (m, 1H) 7.98 (m, 1H) 8.08 (d, J=8.06 Hz, 1H); MS (ES+) m/e 436.1 [M+H]+.
