الإجراء التجريبي

To a solution of tert-butyl [3-(aminomethyl)phenyl]carbamate (0.50 g, 2.2 mmol) and 2,4,5-trichloropyrimidine (0.45 g, 2.5 mmol) in N,N-dimethylformamide (6 mL) was added potassium carbonate (0.62 g, 4.5 mmol). The resultant mixture was stirred overnight at room temperature. The reaction was quenched with water. EtOAc was added and the layers were separated. The aqueous layer was extracted with EtOAc twice. The combined organic layers were washed with water and brine successively, then dried (Na2SO4), filtered, and concentrated. The resulted residue was triturated with methylene chloride and hexanes to give the desired product as an off-white powder (0.75 g, 90%). LCMS for C12H11Cl2N4O2 (M-tBu+H)+: m/z=313.0, 315.0.
