Hydrochloric Acid → HCID 24901139, compound

Participants

Reaction Steps

To a cooled (0° C.) solution of 2-amino-9-[(2R)-2-amino-3-(benzyloxy)propyl]-9H-pyrido[2,3-b]indole-3-carboxamide (61, 81 mg, 0.160 mmol) in chloroform (2 mL) was added iodotrimethylsilane (140 uL, 0.990 mmol). The reaction was stirred under argon, allowed to warm slowly to room temperature and then stirred an additional 16 h. The reaction mixture was filtered and concentrated in vacuo. The crude mixture was purified by reverse phase HPLC (Phenomenex Luna 15 μm C18, aqueous NH4OAc/CH3CN) to provide the product which was then converted to the hydrochloride salt by stirring with a solution of excess hydrochloric acid in methanol to afford 2-amino-9-[(2R)-2-amino-3-hydroxypropyl]-9H-pyrido[2,3-b]indole-3-carboxamide (65, 24 mg, 45%). NH4OAc standard conditions. DAD Retention time =4.76 min. M+H=300. 1H NMR (300 MHz, MeOD-d4): Δ 8.97 (s, 1H), 8.01 (d, J=7.0 Hz, 1H) 7.67 (d, J=7.4 Hz, 1H), 7.52 (t, J=6.9, 1H), 7.38 (t, J=6.9 Hz, 1H), 4.75-4.69 (m, 2H), 3.96-3.81 (m, 2H), 3.71-3.62 (m, 1H).
