A mixture of 5-bromo-3-methyl-3H-imidazo[4,5-b]pyridine (100 mg, 0.47 mmol), 1-(3,4-dihydroisoquinolin-2(1H)-yl)-3-((4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2-yl)amino)propan-2-ol (230 mg, 0.56 mmol), K2CO3 (195 mg, 1.41 mmol) and Pd(dppf)Cl2 (10 mg) in a solution of dioxane (4 mL) and H2O (1 mL). The mixture was stirred then 120° C. for 30 min under microwave mediated heating. After cooling, the catalyst was filtered and the filtrate concentrated and purified by Prep-HPLC to give the desired product 1-(3,4-dihydroisoquinolin-2(1H)-yl)-3-((4-(3-methyl-3H-imidazo[4,5-b]pyridin-5-yl)pyridin-2-yl)amino)propan-22-ol (52 mg, 26.7%). 1HNMR (CH3OD, 400 MHz) δ: 8.38-8.26 (m, 1H), 8.07-7.92 (m, 2H), 7.78-7.68 (m, 1H), 7.33-7.26 (m, 1H), 7.26-7.18 (m, 1H), 7.10-6.97 (m, 3H), 6.96-6.88 (m, 1H), 4.15-4.03 (m, 1H), 3.88 (s, 3H), 3.67 (s, 2H), 3.60-3.50 (m, 1H), 3.46-3.36 (m, 1H), 2.92-2.72 (m, 4H), 2.72-2.55 (m, 2H). LCMS (m/z): 415.2 [M+H]+
