Reaction Steps

To a solution of (S)-tert-butyl (1-oxo-1-((3-(4-(propylamino)-2-((2-(pyridin-4-yl)ethyl)amino)pyrimidine-5-carboxamido)phenyl)amino)propan-2-yl)carbamate (A5, 137 mg) in chloroform (2 mL), trifluoroacetic acid (2 mL) was added at room temperature, and the mixture was stirred at the same temperature for 3 hours. The solvent was evaporated under reduced pressure, and to the obtained residue, saturated aqueous sodium hydrogencarbonate and ethyl acetate were added. The organic layer was separated, and the aqueous layer was extracted with ethyl acetate. The organic layer and the extract were combined, washed with saturated aqueous sodium chloride, and then dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. To the obtained residue, ethyl acetate was added, and the solid matter was taken by filtration, and dried under reduced pressure to obtain (S)—N-(3-(2-aminopropanamido)phenyl)-4-(propylamino)-2-((2-(pyridin-4-yl)ethyl)amino)pyrimidine-5-carboxamide (A6, 75 mg) as white solid.
