Synthetic Route of 6299-85-0, Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 6299-85-0, name is Methyl 2,6-dichloropyrimidine-4-carboxylate. A new synthetic method of this compound is introduced below.
General procedure: To a solution of nitrogen-containing nucleophile (1 eq.) and cesium carbonate (3.0 eq.) in N,N-dimethylformamide (2 mL/mmol) was added 2-haloheterocycle (1.1 eq.). Thereaction was heated to 100 C. and stirred at this temperature for 2 hours. Thereaction was then cooled to room temperature and acidified to pH=1 with 10%aqueous HCl solution if product contains a carboxylic acid, or diluted withwater if neutral. The solution was extracted with twice with dichloromethane.The organic layers were combined, dried with sodium sulfate and concentratedunder vacuum. The crude material was either used directly in subsequentreactions or purified by flash chromatography.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,6299-85-0, its application will become more common.
