Reaction Steps

4-Carbamoyl-4-[4-(pyrimidin-2-ylamino)-benzoylamino]-butyric acid tert-butyl ester was dissolved in dichloroethane (10 mL), followed by the addition of TFA (5 mL). The mixture was stirred at room temperature for 4 hrs. TLC indicated the reaction was complete. Solvents were then removed by rotavap and the residue was washed with EtOAc. A solid was collected by filtration and dried in vacuum oven overnight. 4-Carbamoyl-4-[4-(pyrimidin-2-ylamino)-benzoylamino]-butyric acid was obtained in quantitative yield (285 mg). MS (ESI) m/z 344.
