Procedure

To a stirred solution of N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-3-(ethyl(tetrahydro-2H-pyran-4-yl)amino)-5-(6-formylpyridin-3-yl)-2-methylbenzamide (0.2 g, mmol) in dichloroethane (3 mL) was added morpholine (5 equiv.) in 5 mL MeOH and acetic acid (2 equiv.) and the mixture was stirred at room temperature for 15 minutes. Then NaBH3CN (1.5 equiv.) was added and the reaction stirred at room temperature for 16 hours. After completion (monitored by TLC), aqueous sodium bicarbonate was added to the reaction mixture till pH 7-8, the organic phase was separated and the aqueous phase was extracted with ethyl acetate. The combined organic layers were dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure. The crude compound was purified by column chromatography (100-200 mesh silica gel) eluting with ethyl acetate:hexane to afford the title compound as an off-white solid.
