4923-87-9,With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.4923-87-9,5-Bromobenzothiophene,as a common compound, the synthetic route is as follows.
General procedure: A 25mL Schlenk tube was charged with Cu2O(0.05mmol),ArX (0.5mmol), NHR1R2(0.75mmol), NaOH (1mmol),TBAB (0.1mmol), L1 (0.1mmol) and water (1mL). Themixture was stirred at 130C for 24h. The reaction mixturewas extracted with ethyl acetate (3 ¡Á 10mL), washed withwater and brine, dried over anhydrous Na2SO4,and concentratedin vacuo. The residue was purified by flash columnchromatograph on silica gel (ethyl acetate/petroleum etheras the eluent) to provide the target products 3a-3w.
The synthetic route of 4923-87-9 has been constantly updated, and we look forward to future research findings.
