Reaction Steps

The mixture of 3-(2-methanesulfonyl-pyrimidin-4-yl)-8-(4-methyl-piperazin-1-yl)-imidazo[1,2-a]pyrazine (from Example 46 supra) (100 mg, 0.27 mmol) and [3-amino-3-(3-chloro-phenyl)-propyl]-carbamic acid tert-butyl ester (from Example 62 supra) (307 mg, 1.08 mmol) was heated at 140° C. with stirring for 2 hours. The oil was purified by chromatography (silica gel, 10 g, 200-300 mesh, eluting with dichloromethane:methanol, 50:1 to 20:1) to afford crude (3-(3-chloro-phenyl)-3-{4-[8-(4-methyl-piperazin-1-yl)-imidazo[1,2-a]pyrazin-3-yl]-pyrimidin-2-ylamino}-propyl)-carbamic acid tert-butyl ester. (Yield 123 mg). LC-MS: [M+H]+ 578.
