The mixture of (4-{3-[6-(3-tert-butoxycarbonylamino-1-phenyl-propylamino)-pyridin-2-yl]-imidazo[1,2-a]pyrazin-8-ylamino}-cyclohexyl)-carbamic acid tert-butyl ester (250 mg, 0.38 mmol) in ethanol (4 mL) and concentrated HCl (4 mL) was stirred at room temperature overnight. The reaction mixture was then concentrated under reduced pressure. The residue was purified by preparative-HPLC to give N-{3-[6-(3-amino-1-phenyl-propylamino)-pyridin-2-yl]-imidazo[1,2-a]pyrazin-8-yl}-cyclohexane-1,4-diamine; hydrochloride. (Yield 18 mg).
