実験手順

2-(S)-[(5-Chloro-1H-pyrrolo[2,3-c]pyridine-2-carbonyl)amino]-3-(4-fluorophenyl)propionic acid (100 mg, 0.28 mmol), 3-hydroxyazetidine hydrochloride (Heterocycles, 2002, 56(1–2), 433–442; 30 mg, 0.28 mmol) and HOBt (37 mg, 0.28 mmol) were dissolved in DMF (5 ml) and DIPEA (0.14 ml, 0.83 mmol). After 5 min, EDCI (69 mg, 0.36 mmol) was added and the reaction mixture stirred at rt for 16 h. The solvent was removed in vacuo and the residue triturated with water. Purification by chromatography on silica gel eluting with methanol:dichloromethane (1:49 to 3:97) gave the title compound as a yellow solid. δH (CD3OD): 3.08–3.21 (2H, m), 3.58–3.63 (0.5H, m), 3.84–3.91 (0.5H, m), 4.03–4.09 (0.5H, m), 4.25–4.32 (0.5H, m), 4.38–4.94 (4H, m), 7.03–7.12 (2H, m), 7.15–7.19 (1H, m), 7.30–7.38 (2H, m), 7.68 (1H, s), 8.59 (1H, s); RT=3.32 min.
