Sodium Carbonate → HCID 14623120, compound

Participants

Reaction Steps

Phosphoryl chloride (5 g) was added to the solution of 4-o-chlorophenyl-6-hydroxy-2-(6-methyl-2-pyridinyl)pyrimidine (5 g) in toluene (100 ml). The mixture was heated under reflux for 1 hour and left to stand to room temperature. Aqueous sodium carbonate solution was added thereto until the reaction solution became about pH 8 to be separated into two layers. Toluene layer was washed with water and dried over anhydrous magnesium sulfate. The toluene layer was concentrated under reduced pressure to obtain 4-chloro-6-o-chlorophenyl-2-(6-methyl-2-pyridinyl)pyrimidine (4.6 g).
