Reaction Steps
A mixture of {4-[3-(6-bromo-pyridin-2-yl)-imidazo[1,2-a]pyrazin-8-ylamino]-cyclohexyl}-carbamic acid tert-butyl ester (from Example 40 supra) (0.244 g, 0.5 mmol), 2-chloro-benzylamine (0.143 g, 1.0 mmol), Pd2(dba)3 (30 mg), Davephos (40 mg), NaOtBu (100 mg, 0.1 mmol) in dioxane (12 mL) in a sealed tube was bubbled with N2 for several minutes and then heated under N2 at 110° C. overnight. The solution was then cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure. The residue was purified by chromatography (CH2Cl2:MeOH, 100:1) to give (4-{3-[6-(2-chloro-benzylamino)-pyridin-2-yl]-imidazo[1,2-a]pyrazin-8-ylamino}-cyclohexyl)-carbamic acid tert-butyl ester. (Yield 227 mg, 83%).
