The title compound is synthesized according to General Procedure A. 100 mg of 2-[2-(2-amino-4-methylpyridin-6-yl)ethyl]-6-bromo-3H-imidazo[4,5-b]pyridine in 5.0 ml dioxane, 903 μl Na2CO3 solution, 65 mg of 3,5-dichlorophenylboronic acid, 13 mg of PdCl2(PCy3)2, 120° C. for 64 h. During extraction with 20 ml of CH2Cl2/H2O the title compound starts precipitating in the organic layer. Subsequently, 37 mg of the pure title compound can be obtained as a colorless powder after filtration and lyophilization from 2.0 ml dioxane and 1.0 ml water. M.p. 224° C. ESI-MS: 398.3, 400.2, 402.3 (MH+; 100%, 65%, 13%). TLC: Rf=0.24 (dichloromethane/methanol 10:1).
