Some common heterocyclic compound, 924-99-2, name is Ethyl 3-(dimethylamino)acrylate, molecular formula is C7H13NO2, 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. Recommanded Product: 924-99-2
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 × 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.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 924-99-2, its application will become more common.
