Potassium Carbonate → 2,5-Dichloro-N-(3-methoxybenzyl)pyrimidin-4-amine

Participants

Reaction Steps

To a solution of 3-methoxybenzylamine (0.75 g, 5.4 mmol) and 2,4,5-trichloropyrimidine (1.1 g, 6.0 mmol) in N,N-dimethylformamide (20 mL) was added potassium carbonate (2.3 g, 16 mmol). The resulting mixture was stirred overnight at room temperature. The reaction was quenched with water. Ethyl acetate (“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 successively, then dried (Na2SO4), filtered, and concentrated. The crude product was purified by silica gel column chromatography to give the desired product as a white powder (1.43 g, 92%). LCMS for C12H12ClN3O (M+H)+: m/z=284.0, 286.0.
