Reaction Steps
2-bromoethylether (3.65 g), potassium carbonate (8.29 g), and N,N-dimethylformamide (75 mL) were added to 2-amino-4,6-dichloropyrimidine (2.46 g), and the mixture was refluxed for 3 hours while heated. Subsequently, the reaction mixture was diluted with ethyl acetate, was washed with water, and was dried over anhydrous sodium sulfate. The solvent was removed and the resulting residue was purified on a silica gel column chromatography (hexane:ethyl acetate=5:1) to obtain 4,6-dichloro-2-(morpholine-4-yl)pyrimidine (985 mg, 28%).
