Reference of 105742-66-3, 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 105742-66-3, name is 4,5-Dichloro-2,6-dimethylpyrimidine. This compound has unique chemical properties. The synthetic route is as follows.
General procedure: Compound 5 was synthesized as described.33 Compounds 6 and 7were synthesized in our previous work.34 Compounds 4 (5 mmol), 7(5 mmol) and anhydrous potassium carbonate (5 mmol, 0.69 g) wereadded to a mixed solvent of dimethyl formamide (20 mL) and water(10 mL), and then refluxed for 2-4 h. The progress was monitored byTLC. After the reaction was complete, the reaction solution was pouredinto saturated saline and extracted with ethyl acetate (3¡Á80 mL). Theextract was dried, filtered, and the solvent was removed under reducedpressure to give a crude product. Recrystallization from the mixedsolvent of petroleum ether and ethyl acetate gave pure target compoundsO1-17 (Scheme 2).
According to the analysis of related databases, 105742-66-3, the application of this compound in the production field has become more and more popular.
