The mixture of (2-{6-[8-(4-methyl-piperazin-1-yl)-imidazo[1,2-a]pyrazin-3-yl]-pyridin-2-ylamino}-2-phenyl-ethyl)-carbamic acid tert-butyl ester (30 mg, 0.06 mmol) and concentrated HCl (3 mL) in ethanol (3 mL) was stirred at room temperature for 15 hours. The reaction mixture was then concentrated under reduced pressure to give N1-{6-[8-(4-methyl-piperazin-1-yl)-imidazo[1,2-a]pyrazin-3-yl]-pyridin-2-yl}-1-phenyl-ethane-1,2-diamine; hydrochloride. (Yield 40 mg). 1HNMR (300 MHz, CD3OD): δ 8.54 (brs, 1H), 8.13 (s, 1H), 7.64-7.46 (m, 3H), 7.31-7.10 (m, 5H), 6.92 (d, 1H, J=8.1 Hz), 5.44 (brs, 3H), 3.93 (brs, 2H), 3.72-3.69 (m, 2H), 3.52-3.34 (m, 4H), 2.92 (s, 3H). LC-MS: [M+H]+ 429.
