Reaction Steps
To a stirred solution of tert-butyl 4-(3-(cyclopentyl(methyl)amino)-5-(((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)carbamoyl)-4-methylphenyl)-5,6-dihydropyridine-1(2H)-carboxylate (0.800 g, 1.45 mmol) in DCM was added TFA (3 mL) and the reaction mixture was stirred at RT for 2 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 crude material which was purified by preparative HPLC to afford the desired compound (0.620 g, 95%).
