Application of 1402838-08-7, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 1402838-08-7 name is 2-(1-Trityl-4-imidazolyl)benzaldehyde, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
To a three-necked flask was added 2- (1-trityl-1H-imidazole-4-) benzaldehyde (400 mg, 0.97 mmol)Acetylcyclohexane (122 mg, 0.97 mmol)And anhydrous tetrahydrofuran (5 ml)Under nitrogen protection,A solution of sodium ethoxide (85 mg, 1.25 mmol) in ethanol was added at room temperature,Stir at room temperature for 3 h, spin dry solvent,Saturated ammonium chloride (10 ml) was added,The organic layer was extracted with ethyl acetate and dried over anhydrous sodium sulfate. The solvent was dried, acetic acid (1 ml) and ethanol (5 ml) were added, stirred at 90 C for 3 h, cooled to room temperature, and saturated sodium carbonate was added to adjust pH = 10 , Extracted with ethyl acetate, the combined organic layers were dried over anhydrous sodium sulfate,Concentrated solvent,Purification by column chromatography on silica gel afforded compound 9 (210 mg, yield 77%
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 2-(1-Trityl-4-imidazolyl)benzaldehyde, and friends who are interested can also refer to it.
