Procedure

The solution of (3-{6-[8-(4-methyl-piperazin-1-yl)-imidazo[1,2-a]pyrazin-3-yl]-pyridin-2-ylamino}-3-phenyl-propyl)-carbamic acid tert-butyl ester (44 mg, 0.08 mmol) in ethanol (4 mL) and concentrated HCl (4 mL) was stirred at room temperature for 15 hours. The reaction mixture was then concentrated under reduced pressure. The residue was suspended in CH2Cl2 and 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-propane-1,3-diamine; hydrochloride. (Yield 25 mg). 1H NMR (300 MHz, CD3OD): δ 8.39 (s, 1H), 8.15 (s, 1H), 7.61 (t, 1H, J=5.7 Hz), 7.40-7.48 (m, 7H), 6.78 (brs, 1H), 5.39 (brs, 1H), 5.01 (brs, 1H), 3.81-3.66 (m, 4H), 3.37 (brs, 2H), 3.12-2.91 (m, 7H), 2.16-2.14 (m, 2H). LC-MS: [M+H]+ 443.
