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) (170 mg, 0.36 mmol) and compound (3-amino-3-phenyl-propyl)-carbamic acid tert-butyl ester (from Example 53 supra) (361 mg, 1.44 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-tert-butoxycarbonylamino-1-phenyl-propylamino)-pyrimidin-4-yl]-imidazo[1,2-a]pyrazin-8-ylamino}-cyclohexyl)-carbamic acid tert-butyl ester. (Yield 110 mg).
