New downstream synthetic route of 69045-79-0

Statistics shows that 69045-79-0 is playing an increasingly important role. we look forward to future research findings about 2-Chloro-5-iodopyridine.

Application of 69045-79-0, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.69045-79-0, name is 2-Chloro-5-iodopyridine, molecular formula is C5H3ClIN, molecular weight is 239.4415, as common compound, the synthetic route is as follows.

General procedure: In a glove box, a flame-dried pressure Schlenk tube was charged with NaI(0.3 equiv). The Schlenk tube was taken out of the glove box and charged with amide 1 (1.5equiv), iodopyridine reagent (1 equiv), Ag2CO3 (1.5 equiv), (BnO)2PO2H (0.2 equiv) andPd(OAc)2 (0.1 equiv). DMA and Toluene (1:20 in v/v ratio, 0.1 M) were added. The tube wastightly closed and flushed with argon by three freeze-pump-thaw cycles. The mixture was stirredat 130 C for 24 h. Subsequently, it was diluted with EtOAc (40 mL) and washed with brine (2 ¡Á20 mL) and water (20 mL). The organic layer was dried over Na2SO4, filtered and concentrated invacuo. The crude product was purified by flash chromatography (hexane/ EtOAc in 85/15 to 50/50v/v ratio). Unless otherwise noted, the reactions were run on 0.1 mmol scale.

Statistics shows that 69045-79-0 is playing an increasingly important role. we look forward to future research findings about 2-Chloro-5-iodopyridine.
