4265-25-2,With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.4265-25-2,2-Methylbenzofuran,as a common compound, the synthetic route is as follows.
A solution of 16-g (2.89 g, 21.91 mmol) dissolved in tetrahydroffiran (80 mE) was cooled to 5 C., and then N135 (4.68 g, 26.29 mmol) was slowly added thereto. The reactionsolution was reacted at normal temperature overnight, and then poured into sodium thiosulfate solution, and extracted with ethyl acetate (80 mLx3). The combined organic phase was dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluted with petroleum ether) to obtain compound 16-f (2.57 g, yield 56%) as a colourless liquid. ?H NMR (400 MHz, CDC13-MeOD): oe 7.37-7.3 1 (m, 2H), 7.20-7.18 (m, 2H), 2.40 (s, 3H).
4265-25-2 2-Methylbenzofuran 20263, abenzofuran compound, is more and more widely used in various fields.
