Reaction Steps

5-(1-methyl-1,2,3,6-tetrahydropyridin-4-yl)-3-{1-[4-(morpholin-4-ylcarbonyl)phenyl]-1H-1,2,3-triazol-4-yl}-1H-indazole (20 mg; 0.04 mmol; 1.0 eq.) was dissolved in MeOH (3 mL) and Pd/C (moistened, 50% water; 100 mg) was added. The reaction mixture was hydrogenenated at RT for two days in a Parr instrument (35 bars). Reaction mixture was filtered through a celite pad and dried under vacuum to give the title compound as a beige solid (14 mg, 70%). 1H NMR (300 MHz, DMSO-d6) δ 9.37 (s, 1H), 8.25-8.09 (m, 3H), 7.73-7.62 (m, 2H), 7.64-7.49 (m, 1H), 7.40-7.29 (m, 1H), 3.81-3.39 (m, 8H), 2.98-2.56 (m, 4H), 2.22 (s, 3H), 2.06-1.66 (m, 5H). HPLC (Condition A): Rt 3.86 min (purity 87.8%). MS (ESI+): 472.3, MS (ESI−): 470.2.
