Synthetic Route of 5414-19-7, These common heterocyclic compound, 5414-19-7, name is 1-Bromo-2-(2-bromoethoxy)ethane, 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.
To a solution of the product of Part E (6.8 g, 15.5 mmol), potassium carbonate (Aldrich, 7.5 g, 54.3 mmol), and 18-crown-6 (Aldrich, 0.5 g, cat. amt) in N,N-dimethylformamide (30 ml) was added dibromo-diethylether (Aldrich,2.9 ml, 23.2 mmol). The mixture was heated at 60 C. for 18 hr, and then worked up by cooling and pouring into water (50 ml). The mixture was extracted via ethylacetate (2?-150 ml). The organics were combined and washed with 5% HClaq (1?-50 ml), water (1?-100 ml), and brine (2?-100 ml); dried over Na2SO4; and concentrated to afford a yellow oil that solidified. The solid was recrystallized from methanol to produce the desired compound in the form of a white solid (4.8 g, 76% yield). 1H NMR was consistent with the desired structure.
The synthetic route of 5414-19-7 has been constantly updated, and we look forward to future research findings.
