Reaction Steps

Part C: To a solution of tert-butyl 4-(1-phenyl-1H-tetrazol-5-yl)piperidine-1-carboxylate (0.165 g, 0.50 mmol) in 1,4-dioxane (10 mL) at 25° C. was added 4.00 N HCl in 1,4-dioxane (10 mL), and the mixture was stirred at 25° C. for 16 h. The mixture then was concentrated under vacuum. The resulting solids were dissolved in DMF (10 mL). To this solution was added sequentially 2-(4-fluoro-7-(1H-1,2,3-triazol-1-yl)-1H-pyrrolo[2,3-c]pyridin-3-yl)-2-oxoacetic acid (0.137 g, 0.50 mmol), N-methylmorpholine (0.165 mL, 1.50 mmol), and TBTU (0.176 g, 0.55 mmol), and the mixture was stirred at 25° C. for 24 h. The reaction mixture was filtered, and the filtrate was concentrated under vacuum. The residue was dissolved in hot methanol, and the solution then was allowed to cool slowly to room temperature. The precipitate was recovered by filtration, washed with methanol, and dried under vacuum to provide 1-(4-fluoro-7-(1H-1,2,3-triazol-1-yl)-1H-pyrrolo[2,3-c]pyridin-3-yl)-2-(4-(1-phenyl-1H-tetrazol-5-yl)piperidin-1-yl)ethane-1,2-dione (0.142 g) as an off-white solid; mp: 257-258° C.; HRMS: 487.1740 (M+H)+ [calc'd: 487.1755]; 1H NMR (500 MHz, DMSO-D6) δ 13.06 (br s, 1H), 9.02 (s, 1H), 8.32 (d, 1H, J=1.8 Hz), 8.30 (s, 1H), 8.12 (s, 1H), 7.58 (s, 5H), 4.37 (m, 1H), 3.67 (m, 1H), 3.32 (m, 1H), 3.25 (m, 1H), 3.03 (m, 1H), 2.01 (m, 1H), 1.88 (m, 1H), 1.83-1.70 (m, 2H).
