Reaction Steps
NaH (60% dispersion in oil, 0.201 g, 5.02 mmol, 2 eq) was added to a stirred solution of 4-chloro-6-methoxypyrimidin-2-amine (0.400 g, 2.51 mmol, 1 eq, Aldrich) and MeI (0.5 ml, 1.07 g, 7.52 mmol, 3 eq) in 2 ml anhydrous DMF at 0° C. After 1 h the reaction was quenched with water and diluted with EtOAc. The layers were separated. 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 0.180 g (0.96 mmol, 38% yield) of 4-chloro-6-methoxy-N,N-dimethylpyrimidin-2-amine.
