Reaction Steps

To a stirred solution of 3-(ethyl(tetrahydro-2H-pyran-4-yl)amino)-N-((4-isopropyl-6-methyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-2-methyl-5-(6-(piperazin-1-yl)pyridin-3-yl)benzamide (0.3 g, 0.51 mmol) and 1-methylpiperidin-4-one (0.086 g, 0.76 mmol) in dichloroethane (5 mL), acetic acid (0.18 g, 3.06 mmol) was added and reaction stirred at room temperature for 20 minutes. Then sodium triacetoxyborohydride (0.33 g, 1.55 mmol) was added at 0° C. and reaction stirred at room temperature for 2 h. On completion, reaction was quenched with aqueous sodium bicarbonate, organic phase was separated and aqueous phase was extracted with dichloromethane. Combined organic layers were dried over sodium sulphate and concentrated under reduced pressure to give crude material was purified by prep. HPLC to afford the title compound (0.12 g, 34.38%).
