To a stirred mixture of 1-((3-bromophenyl)amino)-3-(3,4-dihydroisoquinolin-2(1H)-yl)propan-2-ol (120 mg, 0.33 mmol) in dioxane:H2O (15 mL, 2:1) was added 1-methyl-6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-benzo[d]imidazole (93.6 mg, 0.33 mmol), Cs2CO3 (323 mg, 0.99 mmol) and then Pd(dppf)Cl2 (10 mg). The mixture was degassed by N2 for 4 times and then stirred at 100° C. for 16 hours. The reaction mixture was quenched with water (30 mL), extracted with EA (30 mL×3). The combined extracts were washed with brine (30 mL), dried over anhydrous Na2SO4 and concentrated. The residue was purified by prep-HPLC to afford the title compound (46 mg, 34%). 1HNMR (CDCl3, 400 MHz) δ: 7.87 (s, 1H), 7.83-7.81 (m, 1H), 7.55-7.52 (m, 2H), 7.29-7.25 (m, 1H), 7.15-7.10 (m, 3H), 7.04-6.98 (m, 2H), 6.92 (s, 1H), 6.66-6.64 (m, 1H), 4.18-4.11 (m, 1H), 3.89-3.83 (m, 4H), 3.70-3.64 (m, 1H), 3.42-3.38 (m, 1H), 3.21-3.14 (m, 1H), 3.02-2.94 (m, 3H), 2.71-2.61 (m, 3H). LCMS (m/z): 413.2 [M+H]+
