Synthetic Route 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.
In a 1 L reaction vessel Intermediate A-3 (25 g), Phenylboronic acid (10.74 g), & lt; RTI ID = 0.0 & gt; Pd (PPh3) 4 (3.05 g), K2CO3 (24.3 g) , THF (333 mL) and distilled water (166 mL) were put together, And refluxed under nitrogen for 12 hours. After completion of the reaction, the reaction mixture was cooled to room temperature, and the aqueous layer was removed. The organic layer was washed with 5% brine (500 mL) And once with distilled water (500 mL). The organic layer obtained was dried over MgSO4, the solvent was removed, and ethyl acetate: n-hexane (= 3: 97) The residue was purified by silica gel column chromatography Purification yielded intermediate A-2 (12.4 g).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 73290-22-9, 2-Bromo-5-iodopyridine, other downstream synthetic routes, hurry up and to see.
