A mixture of 1-(7-bromo-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, 0.2 mmol), potassium carbonate (26 mg, 0.2 mmol), copper (13 mg, 0.2 mmol) and 3-aminopyrazole (100 uL, 1 mmol) in N-methylpyrrolidinone (0.5 mL) was heated at 160° C. for 5 h. Solvent was removed in vacuum and residue was dissolved in DMF and purified using reverse phase prep HPLC to afford 1-(7-(3-amino-1H-pyrazol-1-yl)-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 (15.9 mg) as a pale yellow solid; 1HNMR (500 MHz, DMSO) δ 8.34 (d, J=2.0 Hz, 1H), 8.29 (d, J=1.5 Hz, 1H), 8.03 (s, 1H), 7.70-7.58 (m, 5H), 5.92 (d, J=2.5 Hz, 1H), 5.25 (m, 2H), 3.71 (m, 2H), 3.47 (m, 2H), 3.32 (m, 2H), 3.16 (m, 2H). LCMS: m/e 502 (M+H)+, ret time 1.26 min (method 3); and 1-(7-(5-amino-1H-pyrazol-1-yl)-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 (8.8 mg) as a pale yellow solid; 1HNMR (500 MHz, CDCl3) δ 8.21 (m, 1H), 8.11 (bs, 1H), 7.60 (m, 6H), 6.94 (m, 2H), 5.52 (m, 1H), 3.71 (m, 2H), 3.47 (m, 2H), 3.31 (m, 2H), 3.16 (m, 2H); LCMS: m/e 502 (M+H)+, ret time 1.26 min (method 3).
