With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.84594-78-5,6-Nitro-2,3-dihydrobenzofuran-5-amine,as a common compound, the synthetic route is as follows.
84594-78-5, Isoamylnitrite (3 equiv) was added dropwise to a solution of 13 or 14(1 equiv) in anhydrous THF at 0C. The reaction mixture was stirred at 0C for 15 min and then refluxed for 3 h. The solution was cooled to room temperature, water (50 mL) was added, and the solution was extracted with ethyl acetate (350 mL). The organic layer was washed with brine, dried over MgSO4, then evaporated and purified by column chromatography with a gradient eluent of EA/n-hexane (2-8%) to give 15 (70%) as a yellow solid or 16 (74%) as a yellow solid.
84594-78-5 6-Nitro-2,3-dihydrobenzofuran-5-amine 13069187, abenzofuran compound, is more and more widely used in various.
