Related Products of 82998-57-0, 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. 82998-57-0 name is 3-Iodo-4-methylbenzoic acid, 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.
Add 2 drops of DMF into 628 mg 3-iodo-4-methylbenzoic acid (2.2 mmol) in 20 mL SOCl2 and reflux for 2 h. After vacuum evaporation of SOCl2, add 6.0 mL anhydrous THF and get the pale yellow solution. Dissolve the product from step 1, 524 mg 5-(4-methyl-1H-imidazol-1-yl)-3-(trifluoromethyl)-benzenamine (2.0 mmol) in 6.0 mL anhydrous THF and add 10 mmol Et3N, and the pale yellow solution prepared previously is added drop wise till it is all added. The reaction mixture rises to room temperature for 1 hr. The reaction was quenched with addition of brine and extracted with EtOAc. The combined extraction organic layers was dried and concentrated under vacuum, the residue was purified through column chromatography to afford 873 mg desired product. (90%) MS (ESI), m/z: 486 (M++H+).
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 3-Iodo-4-methylbenzoic acid, and friends who are interested can also refer to it.
