To a stirred mixture of 1-((6-bromopyridin-2-yl)amino)-3-(3,4-dihydroisoquinolin-2(1H)-yl)propan-2-ol (130 mg, 0.36 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 (102 mg, 0.396 mmol), Cs2CO3 (351 mg, 1.08 mmol) and then Pd(dppf)Cl2 (10 mg). The mixture was degassed with N2 4 times and stirred at 25° C. for 16 hours. The reaction mixture was quenched with water (20 mL), extracted with EA (20 mL×3). The combined extracts were washed with brine (20 mL), dried over anhydrous Na2SO4 and concentrated. The residue was purified by prep-HPLC to afford the title compound (12 mg, 8%). 1HNMR (CH3OD, 400 MHz) δ: 8.05 (s, 1H), 7.88-7.87 (m, 2H), 7.83-7.80 (m, 1H), 7.50 (t, J=8.0, 1H), 7.13-7.11 (m, 4H), 7.01-7.00 (m, 1H), 6.40 (d, J=4.0, 1H), 5.00 (s, 1H), 4.45 (br, 1H), 4.11-4.13 (m, 1H), 3.82-3.61 (m, 6H), 3.52-3.45 (m, 1H), 2.91 (s, 3H), 2.81-2.63 (m, 3H). LCMS (m/z): 414.2 [M+H]
