Application of 592-55-2, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 592-55-2 name is 1-Bromo-2-ethoxyethane, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
Under ice-cooling, sodium hydride (60% in oil, 1.44 g, 36.0 mmol) was added to a solution of 3-bromo-2-methyl-1H-indole (6.30 g, 30.0 mmol) in N,N-dimethylformamide (30 mL) by small portions, and the mixture was stirred under a nitrogen atmosphere at the same temperature for 1 hr. 2-Bromoethyl ethyl ether (5.07 mL, 45.0 mmol) and sodium iodide (0.747 g, 4.50 mmol) were added to the reaction mixture, and the mixture was stirred at 70C for 6 hr. The reaction mixture was concentrated under reduced pressure, water was added and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane-25% ethyl acetate/hexane) to give the title compound (6.30 g, yield 74%) as a dark-purple oil. MS m/z 282 (MH+).
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 1-Bromo-2-ethoxyethane, and friends who are interested can also refer to it.
