Reaction Steps

A solution of 5-bromo-3-(cyclopentylamino)-N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-2-methylbenzamide (1 equiv.), (4-(morpholinomethyl)phenyl)boronic acid (1.2 equiv.) and Pd(PPh3)4 (0.1 equiv.) in 1,4-dioxane (4 mL) was purged with argon for 10 min. Then, 2 M Na2CO3 solution (3.6 equiv.) was added to it and argon was purged again for 10 min. The reaction mixture was stirred at 100° C. for 2 h. After completion of the reaction, water was added to it and extraction was carried out using 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 over silica gel (60-120 mesh size) to afford 5-(cyclopentylamino)-N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-4-methyl-4′-(morpholinomethyl)-[1,1′-biphenyl]-3-carboxamide which was further purified using preparative HPLC which gave the TFA salt.
