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. 824-51-1, name is 6-Methyl-1H-pyrrolo[2,3-b]pyridine, molecular formula is C8H8N2, The 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. category: pyridine-derivatives
General procedure: 7-Azaindole derivatives (4.2 mmol) were added to a stirredsuspension of AlCl3 (21.0 mmol, 2.80 g) in DCM (40 mL) placed at icebath. After the mixture was stirred at room temperature for 0.5 h,acetyl chloride (21.0 mmol, 1.49 mL) was added dropwise and theresulting mixture was reacted for 12 h at room temperature. MeOH(20 mL) was added cautiously to quench the reaction, the solventswere removed under reduced vacuum. Then the residue was dissolvedin 40 mL water,1N NaOH (aq) was added to adjust the pH upto 5, and extracted with ethyl acetate (15mL 3). The combinedorganic phase was dried over anhydride sodium sulfate andconcentrated under reduced vacuum. The residue was further purifiedby column chromatography on silica gel using PE/EA as eluentto afford the corresponding acylated product
With the rapid development of chemical substances, we look forward to future research findings about 824-51-1.
