Procedure

To a stirred solution of 6-bromo-1-cyclopentyl-N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-1H-indazole-4-carboxamide (0.25 g, 0.56 mmol), 4-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzyl)morpholine (0.20 g, 0.67 mmol) and Pd(PPh3)4 (0.032 g, 0.027 mmol) in 1,4-dioxane (4 mL) and purged with argon for 10 min. 2M Na2CO3 solution (0.22 g, 2.03 mmol) was then added to it before a further argon purge for 10 min. The reaction mixture was stirred at 100° C. for 3 h. After completion of the reaction, water was added and extraction carried out using 10% MeOH/DCM. The combined organic layers were washed with water, dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure to afford crude material which was purified by column chromatography to give -cyclopentyl-N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-6-(4-(morpholinomethyl)phenyl)-1H-indazole-4-carboxamide (68.4% yield). LCMS: 540.25 (M+1)+; HPLC: 99.15% (@ 254 nm) (Rt; 5.583); 1H NMR (DMSO-d6, 400 MHz) δ 11.51 (bs, 1H), 8.62 (t, 1H, J=4.8 Hz), 8.36 (s, 1H), 8.10 (s, 1H), 7.85 (s, 1H), 7.80 (d, 2H, J=8 Hz), 7.43 (d, 2H, J=8 Hz), 5.88 (s, 1H), 5.34-5.31 (m, 1H), 4.38 (d, 2H, J=4.8 Hz), 3.59-3.58 (m, 4H), 3.52 (s, 2H), 2.38 (m, 4H), 2.21 (s, 3H), 2.11 (s, 3H), 2.04-1.99 (m, 2H), 1.88 (m, 4H), 1.72-1.69 (m, 2H).
