Reaction Steps

To a solution of tert-butyl 4-[4-({4-[4-(1H-indazol-3-yl)-1H-1,2,3-triazol-1-yl]benzoyl}amino)-1H-pyrazol-1-yl]piperidine-1-carboxylate (100 mg; 0.18 mmol; 1.0 eq.) in Dioxane (3 mL) was added HCl 4N solution in 1,4-dioxane (450 μl of a 4N solution in dioxane; 1.80 mmol; 10 eq.) and one drop of water. The resulting suspension was stirred at RT O/N. Solvent were removed under reduced pressure and the residue was suspended in ACN and filtered to afford the title compound as a beige solid (64 mg; 72%). 1H NMR (300 MHz, DMSO-d6) δ 13.45 (brs, 1H), 10.75 (s, 1H), 9.46 (s, 1H), 9.19-8.73 (m, 2H), 8.38 (d, J=8.1 Hz, 1H), 8.32-8.18 (m, 4H), 8.15 (s, 1H), 7.71 (s, 1H), 7.63 (d, J=8.4 Hz, 1H), 7.52-7.39 (m, 1H), 7.27 (t, J=7.5 Hz, 1H), 4.64-4.42 (m, 1H), 3.48-3.30 (m, 2H), 3.05 (s, 2H), 2.27-2.05 (m, 4H). HPLC (Condition A): Rt 3.06 min (purity 95.7%). MS (ESI+): 454.4, MS (ESI−): 452.3.
