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) (0.487 g, 1.0 mmol), benzylamine (0.214 g, 2.0 mmol), Pd2(dba)3 (60 mg), Davephos (80 mg), NaOtBu (140 mg, 1.46 mmol) in dioxane (25 mL) in a sealed tube was bubbled with N2 for several minutes and then heated under N2 at 110° C. for 15 hours. The solution was then cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure. The obtained crude product was purified by preparative-HPLC to give {4-[3-(6-benzylamino-pyridin-2-yl)-imidazo[1,2-a]pyrazin-8-ylamino]-cyclohexyl}-carbamic acid tert-butyl ester. (Yield 80 mg). LC-MS: [M+H]+ 514.
