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. 1402838-08-7, name is 2-(1-Trityl-4-imidazolyl)benzaldehyde, A new synthetic method of this compound is introduced below., Safety of 2-(1-Trityl-4-imidazolyl)benzaldehyde
5-Acetylbenzofuran-2-carboxylic acid methyl ester (0506-89) (200 mg, 0.86 mmol, 1.0 equiv) and2-(1-trityl-1H-imidazol-4-yl)benzaldehyde (0105-1) (534 mg, 1.3 mmol, 1.5 eq.)Soluble in ethanol (10 ml),Concentrated sulfuric acid 5 ml was added dropwise under ice bath conditions.The temperature was raised to 90C and the reaction was stirred for 18 hours.Cool to room temperature, add dropwise to ice water, add ice bath, add sodium hydroxide to adjust the pH>8, ethyl acetate extraction,The liquid was separated, spin-dried, and the crude product was purified by silica gel column chromatography (eluent: dichloromethane/methanol=200/1 to 40/1) to give the product 5-(2-(5H-imidazole)[5,1-a Ethyl isomorpholin-5-yl)acetyl)benzofuran-2-carboxylate (95 mg, 28.5%).
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.
