Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 75175-77-8, name is 3-(4-Fluorophenyl)-N,N-dimethylacrylamide, A new synthetic method of this compound is introduced below., SDS of cas: 75175-77-8
General procedure: With a mixture of N,N-Dimethylenaminones 1 (1.0 mmol), isatins 2 (0.5 mmol), ammonium acetate 3 (1.0 mmol) in AcOH (1 mL) and EtOH-water (1:4) (5 mL), the reaction mixture was stirred at 80 C for 6 h until TLC indicated that the reaction was completed. The reaction mixture was allowed to cool to room temperature, neutralised with a saturated solution of Na2CO3 to pH 8-9, and then was extracted with ethyl acetate (2 ¡Á 30 mL). The organic phase was washed with water (20 mL) and the organic layer dried over Na2SO4, and concentrated under reduced pressure. The crude product was chromatographed onsilica gel (200-300 mesh) using a mixture of petroleum ether and ethyl acetate as eluent to afford the product 4.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
