Procedure

A stirred solution of tert-butyl 4-((5-bromo-3-(((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)carbamoyl)-2-methylphenyl)(methyl)amino)piperidin-1-carboxylate (1.3 g, 2.39 mmol) in DCM (10 mL) was cooled to 0° C. and TFA (2 mL) was added to it. Reaction mass was stirred at room temperature for 1 h. On completion, reaction was concentrated to dryness. Residue was basified with aqueous sodium bicarbonate till pH 8 and aqueous layer extracted with 20% MeOH/DCM. Combined organic layers were dried over sodium sulfate and concentrated to afford the desired compound (0.9 g, 85%). LCMS: 461.15 (M+1)+; HPLC: 98.52% (@ 254 nm) (Rt; 4.673; Method: Column: YMC ODS-A 150 mm×4.6 mm×5μ; Mobile Phase: A; 0.05% TFA in water/B; 0.05% TFA in acetonitrile; Inj. Vol: 10 μL, Col.
