Yield:-
Reaction Conditions:
with sodium hydroxide in water;trichlorophosphate
Steps:
1.s (Third stage)
(Third stage) In 500 ml of phosphorus oxychloride was added 120.4 g (0.724 mol) of the 2-hydroxy-5-pentylpyrimidine described above, and heated to reflux for 5 hours. Excess amount of phosphorus oxychloride was distilled off under a reduced pressure, and the residue was added into an ice water. The product was extracted with toluene, and the extract was washed with aqueous solution of 2N aqueous solution of sodium hydroxide and water in turn, and dried over anhydrous magnesium sulfate. The solvent was distilled off under a reduced pressure. The residue was purified by distillation to obtain 76.3 g (0.413 mol) of 2-chloro-5-pentylpyrimidine. Yield of this product was 57%.
