Reaction Steps
To a stirred solution of compound 3-(cyclohexyl(methyl)amino)-N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-5-(6-formylpyridin-3-yl)-2-methylbenzamide (1 equiv.) and dimethylamine (5 equiv.) in methanol (10 mL), acetic acid (2 equiv.) was added and reaction stirred at room temperature for 8 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 (0.017 g, 11% yield).
