In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 622392-04-5 as follows. Safety of 2-Bromo-5-iodopyrazine
(1-((1-(trifluoromethyl)cyclobutyl)methyl)piperidin-4-yl)methanol (880 mg, 3.50 mmol) was dissolved in THF (30 mL). At 0 C., NaH (126 mg, 5.25 mmol) was added thereto, and stirred for 30 minutes. 2-bromo-5-iodopyrazine (1.09 g, 3.85 mmol) was added thereto, following with stirring at 55 C. for 10 hours. The reaction mixture was added with water, and extracted with EtOAc. The obtained organic layer was washed with saturated aqueous brine solution, dried over anhydrous MgSO4, and filtered. The filtrate was concentrated under reduced pressure. The obtained material was used without further purifying process
According to the analysis of related databases, 622392-04-5, the application of this compound in the production field has become more and more popular.
