Reaction Steps

MeI (0.46 ml, 1.04 g, 7.32 mmol, 2.4 eq) was added to a stirred solution of 4,6-dichloropyrimidin-2-amine (Aldrich, 0.5 g, 3.05 mmol, 1 eq) in 10 ml anhydrous DMF under Ar. After cooling to 0° C., NaH (0.27 g, 6.71 mmol, 2.2 eq) was added. The reaction was stirred at 0° C. to room temperature overnight. The reaction was quenched with water and extracted with Et2O (×1). The organic layer was washed with water (×3), brine (×1), and dried over Na2SO4. The inorganics were filtered off, and the solvent was removed in vacuo. Purification via flash chromatography yielded 0.4947 g (2.58 mmol, 84% yield) of 4,6-dichloro-N,N-dimethylpyrimidin-2-amine.
