Procedure

To a stirred solution of 5-bromo-N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-3-(ethyl(tetrahydro-2H-pyran-4-yl)amino)-2-methylbenzamide (1 g, 2.15 mmol) and (6-formylpyridin-3-yl)boronic acid (0.539 g, 2.31 mmol) in dioxane/water mixture (15 mL+3 mL), Na2CO3 (0.82 g, 7.74 mmol) was added and solution purged with argon for 15 min. Then Pd (PPh3)4 (0.288 g, 0.25 mmol) was added and argon was purged again for 10 min. Reaction mass was heated at 80° C. for 2 h. On completion, reaction mixture was diluted with water and extracted with 10% MeOH/DCM. Combined organic layers were dried over Na2SO4 and solvent removed under reduced pressure to afford crude material which was purified by column chromatography over silica gel to afford the desired compound (0.60 g, 57%).
