Procedure

To a stirred solution of N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-5-(6-formylpyridin-3-yl)-2-methyl-3-(methyl(tetrahydro-2H-pyran-4-yl)amino)benzamide (1 equiv.) and dimethylamine (5 equiv.) in methanol (10 mL), acetic acid (2 equiv.) was added and reaction stirred at room temperature for 18 h. Then sodium cyanoborohydride (2.5 equiv.) was added at 0° C. and reaction stirred overnight at room temperature. On completion, solvent was removed under reduced pressure and crude material was purified by column chromatography to afford the title compound.
