Some common heterocyclic compound, 103-50-4, name is Benzyl ether, molecular formula is C14H14O, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. 103-50-4
General procedure: A 25 mL Schlenk-type tube equipped with a magnetic stir bar was charged with o-substituted aniline 1a-1f. The reaction tube was evacuated and back-filled with O2. Under oxygen atmospheres, ethers or alcohols 2a-2n and DMSO were added at room temperature, then the reaction mixture was stirred at 120 C for 12 h. The reaction was monitored by TLC. After completion of the reaction, the resulting solution was cooled to room temperature, and neutralized with saturated NaHCO3 aqueous solution. The product was extracted with EtOAc or CHCl3, dried over anhydrous Na2SO4 and concentrated in vacuum. The crude product was purified by flash column chromatography on silica gel to give N-heterocyclic compounds 3.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 103-50-4, its application will become more common.
