실험 절차

To a solution of tert-butyl [5-(2-{5-amino-2-[(tert-butoxycarbonyl)amino]phenyl}ethyl)pyridin-3-yl]carbamate (0.27 g, 0.63 mmol) (prepared in Example C49, step D) and 2,4-dichloro-5-methylpyrimidine (0.103 g, 0.63 mmol) in N,N-dimethylformamide (4 mL) was added potassium carbonate (0.446 g, 3.23 mmol). The resultant mixture was stirred overnight at rt overnight. 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 brine, dried (Na2SO4), filtered and concentrated. The crude was purified by silica gel column chromatography to give the desired product (30 mg, 9%). LCMS for C28H34ClN6O4 (M+H)+: m/z=555.2.
