Reference of 73290-22-9, Adding some certain compound to certain chemical reactions, such as: 73290-22-9, name is 2-Bromo-5-iodopyridine,molecular formula is C5H3BrIN, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 73290-22-9.
Pd2(dba)3 (229 mg, 0.25 mmol), Xantphos (290 mg, 0.5 mmol) and sodium tert-butoxide (2.88 g, 30 mmol) were added to 2-bromo-5-iodopyridine (3.41 g, 12 mmol)And a solution of 1-methylpiperazine (1.0 g, 10 mmol) in toluene (50 ml), heated to 60 degrees Celsius under the protection of argon, and stirred for 24 hours.After the reaction solution was cooled to room temperature, the solid was filtered off, the filter cake was washed with ethyl acetate, and the filtrate was concentrated under reduced pressure to obtain a crude product, which was purified by Combi-flash column chromatography [DCM: MeOH = 100: 0 to 90:10] The compound 1-(6-bromopyridin-3-yl)-4-methylpiperazine was obtained (2.68 g, 79.3%).
According to the analysis of related databases, 73290-22-9, the application of this compound in the production field has become more and more popular.
