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. 5961-59-1, name is 4-Methoxy-N-methylaniline, A new synthetic method of this compound is introduced below., 5961-59-1
General procedure: A 25 mL oven-dried Schlenk tube was sequentially added N-methylaniline 1 or aniline 4 (0.2 mmol), Ethyl Bromodifluoroacetate 2a (81.2 mg, 0.4 mmol), DMF (1ml) and H2O (1 mL) was added under air. The reaction mixture was stirred for 6 h at 110. The solution was then diluted with ethyl acetate (20 mL), washed with brine (10 mL), extracted with ethyl acetate (3*5 mL), dried over anhydrous Na2SO4, filtered and evaporated under vacuum. The crude reaction mixture was purified by column chromatography (silica gel, ethyl acetate/petroleum ether) yielded the desired product 3 or 5.
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.
