実験手順

1-(7-amino-4-fluoro-1H-pyrrolo[2,3-c]pyridin-3-yl)-2-(4-(1-phenyl-1H-tetrazol-5-yl)piperazin-1-yl)ethane-1,2-dione (100 mg, 0.23 mmol) was dissolved in DMF (2 mL) and treated with N,N-dimethyloxamic acid (27 mg, 0.23 mmol), Hunig's base (0.14 mL, 0.8 mmol) and TBTU (81 mg, 0.25 mmol). The reaction mixture was stirred at rt for 18 h. Solvent was removed in vacuum and water was added. A solid precipitated out and it was collected by filtration, dissolved in DMF and purified using reverse phase prep HPLC to afford the title compound as a pale yellow solid (11 mg). 1HNMR (500 MHz, DMSO-D6) δ 8.47 (s, 1H), 8.16 (s, 1H), 7.70-7.50 (m, 5H), 5.76 (m, 1H), 4.10-3.10 (m, 6H), 3.16 (s, 6H). LCMS: m/e 535 (M+H)+, ret time 1.33 min (method 1).
