Related Products of 924-99-2, A common heterocyclic compound, 924-99-2, name is Ethyl 3-(dimethylamino)acrylate, molecular formula is C7H13NO2, 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: All microwave reactions were carried out in a capped (10 mL) microwave-vessel (Borosilicate glass vial sealed) that was placed in a microwave cavity. The pressure was set at 17 bar (average of an effective pressure = 4 bar) with power 75 W. DIEA (3.4 g, 3.4 mmol) was added to a solution of either 2,5-difluoro-4-(pyrrolidin-1-yl) benzoylchloride 12 (0.83 g, 3.4 mmol) or 2,5-difluoro-4-(pyrrolidin-1-yl)benzothioyl chloride 13 (0.88 g, 3.4 mmol) and ethyl-3-(diethylamino)acrylate 14 (0.45 g, 3.1 mmol) in acetonitrile (5 mL). The mixture reaction was held at 100 C for 20 min. After the reaction vessel was cooled to room temperature, the crude product was diluted with water (10 mL) and extracted with ethyl acetate(3 ¡Á 10 mL). The organic layers were combined, dried over Na2SO4, filtered, evaporated and purified by a flash column chromatography (eluent n-hexane: acetone, 3:1)to give the titled compounds.
The synthetic route of 924-99-2 has been constantly updated, and we look forward to future research findings.
