Reaction Steps

To a stirred solution of 6-bromo-N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-1-(piperidin-4-yl)-1H-indazole-4-carboxamide (1 equiv.) and 1-methylpiperidin-4-one (1.5 equiv.) in methanol (5 mL per 0.3 mmol), acetic acid (1 equiv.) was added and reaction stirred at room temperature for 5 h. Then NaBH3CN (1 equiv.) was added and the reaction stirred overnight. On completion, the solvent was removed under reduced pressure and the residue purified by column chromatography (24% yield). LCMS: 555.15 (M+1)+; HPLC: 92.59% (@ 254 nm) (Rt;4.143); 1H NMR (DMSO-d6, 400 MHz) δ 11.52 (s, 1H), 8.60 (t, 1H, J=5.2 Hz), 8.35 (s, 1H), 8.24 (s, 1H), 7.68 (s, 1H), 5.88 (s, 1H), 4.63-4.68 (m, 1H), 4.32 (d, 2H, J=4.8 Hz), 2.97 (d, 2H, J=11.6 Hz), 2.79 (d, 2H, J=10.8 Hz), 2.22-2.40 (m, 3H), 2.19 (s, 3H), 2.13 (s, 3H), 2.11 (s, 3H), 1.99-2.08 (m, 2H), 1.81-1.88 (m, 4H), 1.69 (d, 2H, J=11.2 Hz), 1.43-1.48 (m, 2H).
