Procedimiento

To a solution of 3-methoxyphenethylamine (1.93 mL, 13.2 mmol) and 2,4,5-trichloropyrimidine (1.59 mL, 13.9 mmol) in N,N-dimethylformamide (40 mL) was added potassium carbonate (5.5 g, 40 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 to give the desired product as a yellow gel (3.74 g, 95%). LCMS for C13H14Cl2N3O (M+H)+: m/z=298.0, 300.0.
