実験手順

2-(7-amino-4-fluoro-1H-pyrrolo[2,3-c]pyridin-3-yl)-2-oxoacetic acid (2.3 g, 10.0 mmol) was dissolved in DMF (66 mL) and treated with 1-(1-phenyl-1H-tetrazol-5-yl)piperazine (2.31 g, 10.0 mmol), triethylamine (2.8 mL, 20.0 mmol) and TBTU (3.5 g, 11.0 mmol) and a catalytic amount of DMAP. The reaction mixture was stirred at rt for 18 h. Solvent was removed in vacuum and water was added. A white solid precipitated out and it was collected by filtration and recrystallized with MeOH to afford the title compound (2.4 g) as a yellow solid. 1HNMR (500 MHz, DMSO-D6) δ 8.53 (s, 1H), 7.81 (d, J=4.0 Hz; 1H), 7.75-7.54 (m, 5H), 3.69 (m, 2H), 3.44 (m, 2H), 3.33 (m, 2H), 3.17 (m, 2H). LCMS: m/e 436 (M+H)+, ret time 1.73 min (method 2).
