Procedure

To a stirred solution 5-bromo-N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-3-(ethyl(tetrahydro-2H-pyran-4-yl)amino)-2-methylbenzamide (200 mg, 0.42 mmol) and p-tolyl boronic acid (86 mg, 0.63 mmol) in dioxane (3 mL), aqueous 2M Na2CO3 solution (0.75 mL, 1.51 mmol) was added and solution was purged with argon for 15 min. Then Pd(PPh3)4 (48 mg, 0.04 mmol) was added and argon was purged again for 15 min. Reaction mass was heated at 100° C. for 2 h. On completion, reaction mixture was diluted with water and extracted with 10% MeOH/DCM (3 times). Combined organic layer was dried over sodium sulphate. Removal of the solvent under reduced pressure followed by column chromatographic purification afforded the title compound (150 mg, 73%). LCMS: 488.20 (M+1)+; HPLC: 99.33% (@ 254 nm) (Rt; 5.393; Method: Column: YMC ODS-A 150 mm×4.6 mm×5μ; Mobile Phase: A; 0.05% TFA in water/B; 0.05% TFA in acetonitrile; Inj. Vol: 10 μL, Col.
