Reaction Steps

To 12.4 g (0.1 mole) of 6-ethyl-4-hydroxypyrimidine was added 50 ml of 1,2-dichloroethane, and 18.4 g (0.12 mole) of phosphorus oxychloride was added thereto. The mixture was refluxed by heating for 3 hours. After cooling, water was added to the reaction mixture, and the mixture was extracted with chloroform. The chloroform layer was washed with water and dried over anhydrous sodium sulfate. The solvent was removed under reduced pressure to obtain 10.38 g of 4-chloro-6-ethylpyrimidine as slightly red liquid.
