Participants

Reaction Steps

[(5-Chloro-1H-pyrrolo[2,3-c]pyridine-2-carbonyl)amino]acetic acid (30 mg, 0.12 mmol), 3-hydroxyazetidine hydrochloride (13 mg, 0.12 mmol) and HOBt (16 mg, 0.12 mmol) were dissolved in DMF (3 ml) and DIPEA (43 μl, 0.25 mmol). After 5 min, EDCI (30 mg, 0.15 mmol) was added and the reaction mixture stirred at rt for 16 h. The solvent was removed in vacuo and the residue partitioned between water (20 ml) and DCM (3×20 ml). The combined organics were dried (MgSO4), concentrated in vacuo and the residue purified by chromatography on silica gel eluting with methanol:dichloromethane (1:24) to give the title compound as a white solid. δH (CD3OD): 4.06–4.15 (3H, m), 4.40–4.46 (1H, m), 4.55–4.63 (1H, m), 4.77–4.94 (2H, m), 7.14 (1H, s), 7.71 (1H, s), 8.62 (1H, s); RT=2.82 min.
