The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 13223-25-1, name is 2-Chloro-4,6-dimethoxypyrimidine. This compound has unique chemical properties. The synthetic route is as follows. Product Details of 13223-25-1
Example 5 Synthesis of 3-(4,6-dimethoxy-2-pyrimidinyloxy)-2-pyridinecarboxaldehyde diethylacetal (Compound No. 3) Step (d)] Sodium hydride (7.0 g) was added under stirring to 300 ml of dimethylimidazolidinone, followed by the gradual addition of 37.5 g of 3-hydroxy-2-pyridinecarboxaldehyde diethylacetal at room temperature. Heat was evolved with bubbling so that the temperature of the mixture arose to 55 C. After the mixture was heated for 1 hour at 90-95 C., 31.6 g of 2-chloro-4,6-dimethoxypyrimidine were added. The reaction mixture was heated at 100-120 C. for 8 hours so that the reaction was brought to completion. The reaction mixture was cooled to room temperature, added with 500 ml of water, and then extracted three times with 700 ml portions of ethyl acetate. The organic layers were combined, washed with water and then dried over anhydrous sodium sulfate. The solvent was then distilled out, whereby 87.4 g of an oily residue were obtained. The residue was purified by silica gel chromatography (n-hexane/ethyl acetate=1:1) so that 54.6 g of 3-(4,6-dimethoxy-2-pyrimidinyloxy)-2-pyridinecarboxaldehyde diethylacetate were obtained (yield: 90%).
With the rapid development of chemical substances, we look forward to future research findings about 13223-25-1.
