90843-31-5,With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.90843-31-5,5-Acetyl-2,3-dihydrobenzo[b]furan,as a common compound, the synthetic route is as follows.
To a stirred solution of 1-(2,3-dihydrobenzofuran-5-yl)ethan-1-one (2.0 g, 13.0 mmol) in dry MeOH (20 mL), NaBH4 (0.68 g, 26.0 mmol, Loba chemie) was added slowly at 0 C. The reaction mixture was stirred at rt for 1 h. It was then concentrated under vacuum and the resulting crude product was dissolved in DCM (50 mL), washed with water, brine, dried over anhydrous Na2SO4 and concentrated under reduced pressure. The crude product was used in the next step without further purification. Yield: 91 % (1.83 g).
As the paragraph descriping shows that 90843-31-5 is playing an increasingly important role.
