실험 절차

To a solution of tert-butyl {5-[2-(3-aminophenyl)ethyl]pyridin-3-yl}carbamate (0.20 g, 0.64 mmol) (prepared in Example C19, step B) and 2,4-dichloro-5-fluoropyrimidine (200 mg, 1.2 mmol) in N,N-dimethylformamide (4 mL) was added potassium carbonate (0.430 g, 3.1 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 once. The combined organic layers were washed with water and brine, and then dried (Na2SO4), filtered, and concentrated. The crude was purified by silica gel column chromatography to give the desired product as a light yellow oil (60 mg, 20%). LCMS for C22H24ClFN5O2 (M+H)+: m/z=444.0.
