Reaction Steps

A mixture of [3-(6-bromo-pyridin-2-yl)-imidazo[1,2-a]pyrazin-8-yl]-(2-morpholin-4-yl-ethyl)-amine (from Example 41 supra) (0.403 g, 1.0 mmol), [3-amino-3-(3-chloro-phenyl)-propyl]-carbamic acid tert-butyl ester (from Example 62 supra) (0.427 g, 1.5 mmol), Pd2(dba)3 (60 mg), Davephos (80 mg), K2CO3 (207 mg, 1.5 mmol) in dioxane (25 mL) in a sealed tube was bubbled with N2 for several minutes and then heated under N2 at 130° C. overnight. The solution was then cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure. The residue was purified by preparative-HPLC to give (3-(3-chloro-phenyl)-3-{6-[8-(2-morpholin-4-yl-ethylamino)-imidazo[1,2-a]pyrazin-3-yl]-pyridin-2-ylamino}-propyl)-carbamic acid tert-butyl ester. (Yield 50 mg). LC-MS: 607 [M+H]+ 607.
