A mixture of 6-bromo-1-(4-methoxybenzyl)-1H-benzo[d]imidazole (200 mg, 0.63 mmol), 1-(3,4-dihydroisoquinolin-2-(1H)-yl)-3-(3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenoxy)propan-2-ol (284 mg, 0.69 mmol), K2CO3 (261 mg, 1.89 mmol) and Pd(dppf)Cl2 (50 mg) in dioxane (8 mL) and H2O (2 mL) was stirred at 100° C. for 16 h. The catalyst was filtered and the filtrate concentrated. The residue was then purified by Prep-HPLC to give the title compound (79 mg, 24.2%). 1HNMR(CH3OD, 400 MHz) δ: 8.39 (br, 1H), 8.25 (s, 1H), 7.73-7.68 (m, 1H), 7.64-7.61 (m, 1H), 7.56-7.48 (m, 1H), 7.48-7.42 (m, 1H), 7.28-7.14 (m, 8H), 6.97-6.85 (m, 3H), 5.44 (s, 2H), 4.50-4.45 (m, 1H), 4.35 (s, 2H), 4.10-4.09 (m, 2H), 3.70 (s, 3H), 3.51-3.48 (m, 2H), 3.36-3.31 (m, 2H), 3.19-3.10 (m, 2H). LCMS (m/z): 520.2 [M+H]
