実験手順

The mixture of [4-(3-{6-[(thiophen-2-ylmethyl)-amino]-pyridin-2-yl}-imidazo[1,2-a]pyrazin-8-ylamino)-cyclohexyl]-carbamic acid tert-butyl ester (100 mg, 0.193 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 prepara-HPLC to give N-(3-{6-[(thiophen-2-ylmethyl)-amino]-pyridin-2-yl}-imidazo[1,2-a]pyrazin-8-yl)-cyclohexane-1,4-diamine; hydrochloride. (Yield 30 mg). 1HNMR (300 MHz, CD3OD): δ 8.59-8.56 (m, 1H), 8.38 (brs, 1H), 7.82 (d, 1H, J=9.0 Hz), 7.42-7.34 (m, 1H), 7.16-7.04 (m, 2H), 6.98-6.85 (m, 2H), 6.43-6.39 (m, 1H), 4.70 (d, 2H, J=5.1 Hz), 3.89-3.85 (m, 1H), 3.23-3.07 (m, 1H), 2.20-2.05 (m, 4H), 1.60-1.37 (m, 4H). LC-MS: [M+H]+ 420.
