実験手順

To a solution of 2-amino-9H-pyrido[2,3-b]indole-3-carboxamide (5, 150 mg, 0.663 mmol) in pyridine (7 mL) was added EDC (210 mg, 1.10 mmol), DMAP (85 mg, 0.693 mmol) and benzyloxyacetic acid (142 μL, 0.994 mmol) and the mixture was stirred at RT under an atmosphere of Ar. After 23 h, the reaction was quenched with water (20 mL), poured into a separatory funnel containing EtOAc (100 mL) and washed with water (75 mL). The organic layer was washed with brine (100 mL), dried over sodium sulfate, filtered and concentrated. The crude product was purified by HPLC (Phenomenex Luna 15 μm C18, aqueous HCOOH/CH3CN) to yield 2-amino-9-[(benzyloxy)acetyl]-9H-pyrido[2,3-b]indole-3-carboxamide (28, 54 mg, 22%). NH4OAc standard conditions. DAD Retention time=7.6 min. M+H=375. 1H NMR (300 MHz, DMSO-d6): δ 8.76 (s, 1H), 8.52-8.49 (m, 1H), 8.04 (br s, 1H), 7.83-7.77 (m, 3H), 7.47-7.29 (m, 8H), 5.30 (s, 2H), 4.72 (s, 2H).
