Reaction Steps

To a solution of tert-butyl {2-[2-(3-aminophenyl)ethyl]pyridin-4-yl}carbamate (240 mg, 0.76 mmol) and 2,4-dichloro-5-fluoropyrimidine (134 mg, 0.80 mmol) in N,N-dimethylformamide (3.5 mL) was added potassium carbonate (318 mg, 0.23 mmol). The resultant mixture was stirred overnight at room temperature. The reaction mixture was filtered first to remove K2CO3, followed by quenching 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, then dried (Na2SO4), filtered and concentrated to give the residue, which was purified by silica gel column chromatography to give the desired product as an off-white solid (123 mg, 36%). LCMS for C22H24ClFN5O2 (M+H)+: m/z=444.1.
