Reaction Steps
A mixture of 1-benzyl-6-bromo-1H-benzo[d]imidazole (200 mg, 0.70 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 (314 mg, 0.77 mmol), K2CO3 (290 mg, 2.1 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 was concentrated. The residue was purified by prep-HPLC to give the title compound (108 mg, 31.6%). 1HNMR (CH3OD, 400 MHz) δ: 8.43 (br, 1H), 8.25 (s, 1H), 7.75-7.68 (m, 1H), 7.59-7.48 (m, 2H), 7.33-7.10 (m, 12H), 6.95-6.89 (m, 1H), 5.46 (s, 2H), 4.52-4.46 (m, 1H), 4.43-4.32 (m, 2H), 4.12-4.01 (m, 2H), 3.57-3.47 (m, 2H), 3.40-3.25 (m, 2H), 3.19-3.04 (m, 2H). LCMS (m/z): 490.2 [M+H]+
