Related Products of 109-85-3, These common heterocyclic compound, 109-85-3, name is 2-Methoxyethylamine, 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.
General procedure: To a solution of nitrogen-containing nucleophile (1 eq.) and cesium carbonate (3.0 eq.) in N,N-dimethylformamide (2 mL/mmol) was added 2-haloheterocycle (1.1 eq.). Thereaction was heated to 100 C. and stirred at this temperature for 2 hours. Thereaction was then cooled to room temperature and acidified to pH=1 with 10%aqueous HCl solution if product contains a carboxylic acid, or diluted withwater if neutral. The solution was extracted with twice with dichloromethane.The organic layers were combined, dried with sodium sulfate and concentratedunder vacuum. The crude material was either used directly in subsequentreactions or purified by flash chromatography.
The synthetic route of 109-85-3 has been constantly updated, and we look forward to future research findings.
