Electric Literature of 592-55-2, These common heterocyclic compound, 592-55-2, name is 1-Bromo-2-ethoxyethane, its 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.
A. 2-Ethoxyethoxynitrobenzene 2-Nitrophenol (91.0 g., 0.65 mole), 2-bromoethyl ethyl ether (100.0 g., 0.65 mole), anhydrous potassium carbonate (9.0 g, 0.72 mole) and acetone (1 liter) were refluxed for 65 hours. The reaction mixture was filtered, and the acetone removed by rotary evaporation. The residue was partitioned between 200 ml. of dichloromethane and 100 ml water. The organic phase was further washed with 200 ml. of 10% sodium hydroxide followed by 100 cc of water. The product (58.0 g) was obtained in 42% yield by a vacuum distillation (100-120 C./0.5 mm).
Statistics shows that 1-Bromo-2-ethoxyethane is playing an increasingly important role. we look forward to future research findings about 592-55-2.
