실험 절차

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), [2-amino-2-(3-chloro-phenyl)-ethyl]-carbamic acid tert-butyl ester (from Example 78 supra) (0.406 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 obtained residue was purified by chromatography (CH2Cl2:MeOH, 50:1 to 20:1) to give crude (2-(3-chloro-phenyl)-2-{6-[8-(2-morpholin-4-yl-ethylamino)-imidazo[1,2-a]pyrazin-3-yl]-pyridin-2-ylamino}-ethyl)-carbamic acid tert-butyl ester. (Yield 210 mg). LC-MS: [M+H]+ 593.
