Product 1

HCID 68227054(4-{3-[2-(3-Chloro-benzylamino)-pyrimidin-4-yl]-imidazo[1,2-a]pyrazin-8-ylamino}-cyclohexyl)-carbamic acid tert-butyl ester

Procedure

The mixture of {4-[3-(2-methanesulfinyl-pyrimidin-4-yl)-imidazo[1,2-a]pyrazin-8-ylamino]-cyclohexyl}-carbamic acid tert-butyl ester (from Example 48 supra) (100 mg, 0.212 mmol) and (3-chlorobenzylamine (120.3 mg, 0.849 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 30:1) to afford crude (4-{3-[2-(3-chloro-benzylamino)-pyrimidin-4-yl]-imidazo[1,2-a]pyrazin-8-ylamino}-cyclohexyl)-carbamic acid tert-butyl ester. (Yield 80 mg). LC-MS: [M+H]+ 549.
