To a stirred solution of N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-5-(ethyl(tetrahydro-2H-pyran-4-yl)amino)-4′-formyl-2′,4-dimethyl-[1,1′-biphenyl]-3-carboxamide (410 mg, 0.79 mmol) and morpholine (210 mg, 2.38 mmol) in dichloroethane (10 mL), acetic acid (280 mg, 4.77 mmol) was added and reaction stirred at room temperature for 30 minutes. Then sodium triacetoxyborohydride (580 mg, 2.71 mmol) was added to the reaction mixture at 0° C., allowed to attain room temperature and stirring continued for overnight. On completion, reaction mixture was diluted with dichloromethane, washed with water, saturated aqueous sodium bicarbonate solution and dried over sodium sulphate. Removal of the solvent under reduced pressure followed by column chromatographic purification afforded the title compound (125 mg, 26.76%).
