Related Products of 4983-28-2 , The common heterocyclic compound, 4983-28-2, name is 2-Chloro-5-hydroxypyrimidine, molecular formula is C4H3ClN2O, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
Preparation Example 19 To a mixture of 2-chloro-5-hydroxypyrimidine (4.38 g), potassium carbonate (9.27 g), and N,N-dimethylformamide (79 mL), 2,6-difluoro-3,5-dimethoxybenzyl methanesulfonate (7.89 g) was added followed by stirring at 60 C. for 1 hour. To the reaction mixture, water was added, and the resulting solid was collected by filtration, washed with water, and then dried under reduced pressure to give 2-chloro-5-[(2,6-difluoro-3,5-dimethoxybenzyl)oxy]pyrimidine (8.53 g).
The synthetic route of 4983-28-2 has been constantly updated, and we look forward to future research findings.
