Reaction Steps

The title compound is synthesized according to General Procedure A. 150 mg of 2-[2-(2-amino-4-methylpyridinyl)ethyl]-bromo-3H-imidazo[4,5-b]pyridine in 7.5 ml dioxane, 1.36 ml Na2CO3 solution, 116 mg of 3-benzyloxyphenylboronic acid, 20 mg of PdCl2(PCy3)2, 120° C. for 48 h, 20 ml of CH2Cl2/H2O, 220 mg of crude title compound is purified by recrystallization from 6.0 ml isopropyl alcohol to yield 120 mg of the title compound. M.p. 181° C. ESI-MS: 436.3 (MH+). TLC: Rf=0.30 (dichloromethane/methanol 10:1).
