Reaction Steps

To a solution of tert-butyl {2-[2-amino-3-(aminocarbonyl)-9H-pyrido[2,3-b]indol-9-yl]ethyl}carbamate (xvi-a, 35.0 mg, 0.095 mmol) in MeOH (2 mL) was added conc. HCl (1 mL). The reaction was stirred at RT. After 2 h, the reaction was concentrated and lyophilized to yield 2-amino-9-(2-aminoethyl)-9H-pyrido[2,3-b]indole-3-carboxamide hydrochloride as a white solid (16, 27 mg, 93%). NH4OAc standard conditions. DAD Retention time=4.48 min. M+H=270. 1H NMR (300 MHz, D2O): 8.16 (s, 1), 7.74 (d, J=7.6 Hz, 1H), 7.73-7.42 (m, 1H), 7.36-7.28 (m, 2H), 4.32 (t, J=5.7 Hz, 2H), 3.37 (t, J=5.7 Hz, 2H).
