Continuously updated synthesis method about 21740-00-1

At the same time, in my other blogs, there are other synthetic methods of this type of compound, 5-Bromo-2-iodobenzoic acid, and friends who are interested can also refer to it.

Adding a certain compound to certain chemical reactions, such as: 21740-00-1, name is 5-Bromo-2-iodobenzoic acid, belongs to iodides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 21740-00-1, Recommanded Product: 5-Bromo-2-iodobenzoic acid

5-Bromo-2-iodobenzoic acid (409 mg, 1.25 mmol), A7-(3-dimethylaminopropyl)-iV- ethylcarbodiimide hydrochloride (288 mg, 1.5 mmol ), 1 -hydroxy benzotriazole (135 mg, 1.0 mmol), AVV-diisopropylethylamine (523 pL, 3.0 mmol), and benzylamine (109 pL, 1.0 mmol) were dissolved in anhydrous DMF (5 mL) and stirred at room temperature for 16 hr. The reaction mixture was diluted with an excess of EtOAc and washed five times with water and brine. The organic layer was dried over NarSOy filtered and concentrated. The residue was purified by flash column chromatography (EtOAc : DCM = 0 : 100 to 30 : 70) to give A-benzyl- 5-bromo-2~iodobenzamide (361 mg, 87 %) as a white solid.
