YieldReaction ConditionsOperation in experiment
86% With sodium hydroxide; In water; for 5h;Reflux; To a solution of 4,6-dichloropyrimidin-2-amine (21.2 g, 129.27 mmol) in 200 mL of IN NaOH was added NaOH (4 g, 100.00 mmol) in several batches. The resulting solution was refluxed for 5 hours. The reaction mixture was cooled in a bath of H2O/ice. Adjustment of the pH to 5-6 was accomplished by the addition of CH3COOH. A filtration was performed and the filter cake was collected. The solid was washed with water and dried under an oven with reduced pressure. This resulted in 17 g (86percent) of 2-amino-6-chloropyrirnidin-4(3H)-one as a white solid.
With sodium hydroxide; water; for 5h;Heating / reflux; 2-Amino-4, 6-dichloropyrimidine (10.6 g) was suspended in 1N NAOH (100 mL) and heated to reflux. Additional NaOH(s) (1.0 g) was added after 2 h and 4 h. After 5H, the solution was cooled with an ice bath and neutralized with acetic acid. The white precipitate was filtered, washed with water, and dried on a high vacuum to yield 9.28 g of white solid.
