Reference of 627-42-9, These common heterocyclic compound, 627-42-9, name is 2-Methoxyethyl chloride, 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 solution of ethyl 3,4-dihydroxybenzoate (1.7 g, 9.3 mmol) was placed in a reaction flask and 8 mL of DMF was added to dissolve it. Potassium tert-butoxide (2.0 g, 17.8 mmol) and potassium iodide (1.0 g, 6.0 mmol), and the temperature was raised to 100 C. 2-Chloroethyl methyl ether (3.52 g, 37.2 mmol) was added dropwise and the reaction was continued for 12 h after completion of the dropwise addition. Cooled to room temperature, ice water (200 mL) was added, and extracted three times with ethyl acetate (3 x 200 mL). The organic phase was combined, washed three times with distilled water, three times with saturated brine, dried over anhydrous sodium sulfate overnight, filtered, and the filtrate was evaporated to dryness under reduced pressure to give an oil. The elution system was petroleum ether / ethyl acetate = 1) Ethyl 3,4-bis (2-methoxyethoxy) benzoate.
Statistics shows that 2-Methoxyethyl chloride is playing an increasingly important role. we look forward to future research findings about 627-42-9.
